Final answer:
The correct answer is A) Feature Branch / Target, as tests for user stories generally run on the development or feature branch, and tests during DEPLOYING are executed on the target environment.
Step-by-step explanation:
The question is about the differences between when tests are run for user stories versus during the DEPLOYING process in software development. Tests for user stories typically run on the development or feature branch, which is where new functionality is being worked on away from the main codebase. However, tests executed while DEPLOYING will usually run on the target environment, which is the environment where the software is being deployed, such as a staging or production environment.
Therefore, the correct answer to the student's question, "Unlike user stories, where tests run on the ___, tests executed while DEPLOYING will run on the ___," is A) Feature Branch / Target.
