Consolidate :

The correct answer is: D. Build.

To consolidate means to make something stronger or more solid. It can also mean to bring together or unite things into a single unit. In the context of the question, the correct answer is D because consolidation is a process of building something up, not tearing it down.

A. Weaken is the opposite of consolidate. It means to make something weaker or less strong.

B. Expand means to make something larger or more extensive. It is not the opposite of consolidate, but it is not the correct answer to the question either.

C. Destroy means to ruin or damage something completely. It is the opposite of consolidate.

I hope this helps!
