Why each option

Multi-stage Docker builds optimize image size by allowing only the necessary final artifacts from earlier stages to be copied into a lean production image.

AYesCorrect

Multi-stage Docker builds significantly optimize image size by allowing only the essential build artifacts from an earlier stage (which may contain many build tools and dependencies) to be copied into a separate, final, and much smaller production image.

BNo

This is one of the core advantages of multi-stage builds, enabling developers to create smaller and more efficient Docker images for deployment.
