During release planning, a tester adds value by assessing the testability of user stories. This involves evaluating whether the user stories are clear, concise, and testable. The tester ensures that the acceptance criteria are well-defined and that the stories can be effectively tested within the given timeframe.

Debugging activities typically include reproducing the failure, diagnosing the root cause, and fixing the cause of the failure. Adding new test cases, while important in the overall testing process, is not a direct part of debugging. Debugging focuses on understanding and correcting the issue that caused the failure, rather than expanding the test suite.

Selecting a tester with the required knowledge related to compliance and standards is a correct mitigation option, especially in a highly regulated domain like healthcare. This approach ensures that the tester understands the specific regulatory requirements and standards applicable to the software, thereby reducing the risk of non-compliance. This is more effective than just increasing the number of testers, as it directly addresses the knowledge and expertise needed to mitigate specific product risks​​.

The question is about selecting the correct test values for x based on equivalence partitioning. Equivalence partitioning is a software test design technique that divides the input data of a software unit into partitions of equivalent data from which test cases can be derived. In this case, the given equivalence classes are:

(x \leq -100)

(-100 < x < 100)

(100 \leq x < 1000)

(x \geq 1000)

Option D provides a value from each of these partitions:

For (x \leq -100), it gives -1000.

For (-100 < x < 100), it gives -100 and 100.

For (100 \leq x < 1000), it gives 500.

For (x \geq 1000), it gives 1500.

So, option D covers all four given equivalence classes with appropriate values.
