Question

a large picture made up of small pieces

small pieces of a picture

pictures of a small molecule

Explanation:

A mosaic is typically defined as a large picture or design created by assembling small pieces (like tiles, stones, etc.). The option "a large picture made up of small pieces" aligns with this common understanding. The other options either refer to molecular aspects (not relevant to the general definition of mosaic) or incorrect descriptions (e.g., "small pieces of a picture" doesn't capture the whole - made - from - parts concept as well as the correct option).

Answer:

B. a large picture made up of small pieces
