What is the primary benefit of combining multiple Docker image layers into a single layer?

AIt automatically updates the image to the latest base version

BIt speeds up the build process by skipping all intermediate steps

CIt allows running containers with multiple base images simultaneously

DIt reduces the final image size by eliminating redundant data

Step-by-Step Solution

Solution:

Step 1: Understand Docker layers
Docker images are built in layers, each representing a filesystem change.
Step 2: Effect of squashing
Squashing merges these layers into one, removing redundant or overwritten files.
Final Answer:
It reduces the final image size by eliminating redundant data -> Option D
Quick Check:
