What does the term "Mosaic" refer to?

The term "Mosaic" refers specifically to a picture or pattern created from the assembly of small pieces of materials such as stone, glass, or even ceramic. This art form has been used since ancient times to decorate floors, walls, and ceilings, producing intricate designs that often depict scenes or patterns.

In this context, a mosaic is not merely a collection of materials but a deliberate artistic composition where each piece contributes to the overall image or design. The meticulous placement of these pieces demonstrates a blend of creativity and craftsmanship, making "B" the most fitting definition.

The other options, while related to visual arts or nature, do not encapsulate the specific artistic technique and historical significance associated with mosaics.
