A web client submits a request to http://localhost:8081/books/0471767840. The value `0471767840` is captured by a Set Variable transformer to a variable named bookISBN.
What is the DataWeave expression to access bookISBN later in the flow?

What is the DataWeave expression to access bookISBN later in the flow?
The correct DataWeave expression to access the variable bookISBN, set by a Set Variable transformer, is vars.bookISBN. In MuleSoft, variables set within the flow using the Set Variable component are accessible via the vars prefix.
Correct is C
C is correct.
C is correct
C is correct. Set Variable sets a variable in the current Mule event, and the variables then travel with the Mule event to downstream event processors. You can access any variable with DataWeave using vars. So if you set a variable named lastMessage, you can access it as vars.lastMessage.
