Explanation

The question is missing the definitions of items a–e, which is a formatting issue in how it was provided. However, based on standard ISTQB software testing principles, this is a classic question about the defect lifecycle.

Why B (b and c) is correct: After a defect is fixed, the two immediate next steps are confirmation testing (re-testing the specific fix to verify the defect is resolved) and regression testing (verifying the fix hasn't broken other parts of the system). Both must happen together - one without the other is incomplete practice.

Why the distractors are wrong:

• A / E ("a and b") - these are identical choices, which signals a trap. If the first item (a) is something like "raise a change request," that precedes the fix, not follows it.
• C ("c and d") - skips confirmation testing, jumping straight to regression and then some later activity like production release, which is premature.
• D ("c and e") - similarly skips the re-test of the actual defect, which must come before any downstream steps.

Memory tip: Remember "Fix → Confirm → Regress" in that order. You always confirm the fix worked first, then run regression to check for collateral damage. Think of it as: "Did we fix it? Did we break anything else?"

Note: The full list of sub-items (a–e) appears missing from this question. If you have the complete version, the same logic applies - look for the pair that maps to confirmation + regression testing.
