I have doubts as to why the correct answer is not A.

The Nexus Guide (https://www.scrum.org/resources/nexus-guide) says on page two: "The work must be organized and sequenced, the DEPENDENCIES RESOLVED, and the outcomes staged." So A should be right.

According to NEXUS: "Cross-Team Refinement of the Product Backlog reduces or eliminates cross-team dependencies within a Nexus. The Product Backlog must be decomposed so that dependencies are transparent, identified across teams, and removed or minimized."

Based on the Scrum Guide, the key concern when multiple Development Teams are working from the same Product Backlog is: A. Minimizing dependencies between teams. Scrum emphasizes the importance of minimizing dependencies between Development Teams to allow for greater flexibility and agility in delivering increments of the product. This is mentioned in the Scrum Guide to ensure that teams can work independently and efficiently, contributing to the overall success of the product.

I suggest to vote instead of write that B is wrong, we must click on vote and select option A

This is a trick question. "Key concern". It's about order. You cannot minimize dependencies without clear definition of requirements. So B: Clear definitions trumps A: minimizing dependencies.

When multiple Development Teams are working from the same Product Backlog, a key concern is minimizing dependencies between teams. This helps ensure that each team can work independently and deliver value without being overly reliant on the work of other teams. Reducing dependencies allows for greater flexibility and efficiency in delivering increments of the product during a Sprint. Scrum emphasizes the importance of ensuring that work can be completed within the Sprint without external delays or bottlenecks.

All of you read the question carefully..its asking about what seems to be a major concern qhen multiple teams are working on same PB, so each team can have different understanding so the concern is to get the right balance of requirements, the question isnt asking what the scrum master should do in this situation... please read the question carefully

I think the right answer is A

A is correct

Answer is A. The primary concern when multiple Development Teams work from the same Product Backlog is minimizing dependencies between teams. This is crucial because dependencies can create bottlenecks and impede progress, making it difficult for teams to work efficiently and effectively. By minimizing dependencies, teams can work more independently, reducing the likelihood of delays and enhancing overall productivity. This approach ensures that each team can focus on their tasks without being overly reliant on the progress or completion of tasks by other teams, which is a fundamental aspect of scaling Scrum effectively. https://www.scrum.org/forum/scrum-forum/36163/can-two-teams-work-one-product-backlog

A is correct

A is the correct answer. This question confused me at first. With the Scrum Guide v2020, there is no longer a Developer Team. There are the developers and the Scrum team. The key challenge is to minimize dependencies between the scrum teams

A is the correct answer, from Nexus's guide

Answer should be B. From scrum guide: They use word cohesive which means they are not independet. "If Scrum Teams become too large, they should consider reorganizing into multiple cohesive Scrum Teams, each focused on the same product. Therefore, they should share the same Product Goal, Product Backlog, and Product Owner."
