Is this an advantage of multi-stage builds? Solution: better caching when building Docker images

The correct answer is B. No. Multi-stage builds are primarily for optimizing image size by separating build-time and runtime dependencies, not for improving caching effectiveness during the build process.

Why each option

Multi-stage builds are primarily for optimizing image size by separating build-time and runtime dependencies, not for improving caching effectiveness during the build process.

AYes

The main benefit of multi-stage builds lies in image optimization and build dependency management, not improved caching efficiency.

BNoCorrect

Multi-stage builds focus on reducing the final image size by selectively copying artifacts from previous stages; they do not inherently provide better caching for the build process itself, which relies on Docker's layer caching mechanism.
