E. Isolated environments A benefit of application security in a cloud environment is the concept of isolated environments. Cloud environments can provide the ability to isolate applications and their associated resources from each other. This isolation helps prevent the impact of security incidents or breaches in one application from affecting others. It adds a layer of protection and containment, contributing to overall security and reducing the potential for cross-application vulnerabilities or exploits. The other options (A, B, C, D) do not accurately describe benefits of application security in a cloud environment.
