Show answer & explanation
Correct answer: D
Answer: Statements II and III are correct.
Explanation:
Statement II is correct: a version denotes an instance that is functionally distinct in some way from other instances (for example, a new feature, API change, or bug fix). Versions track functional changes.
Statement III is correct: a release is an instance that is distributed to users outside the development team. The term 'release' emphasizes distribution (e.g., alpha, beta, production releases), not whether a change is functional or nonfunctional.
Statement I is incorrect: describing a version as functionally identical but only nonfunctionally distinct is wrong. Nonfunctional changes alone (like build options or packaging) typically create different builds or configurations, but the term 'version' usually implies functional differences.
Statement IV is incorrect: a release is not defined by being functionally identical but nonfunctionally distinct. Releases are defined by being distributed to external users and may include functional changes; nonfunctional differences alone do not capture the concept of a release.
Quick mnemonic: Version = functional change; Release = distribution to users.
