B Correct answer
Explanation

In multicellular organisms, as the body size increases, individual cells cannot efficiently perform all necessary life functions for the whole organism. Tissues allow for a division of labor, where groups of cells specialize to perform specific tasks like transport or support. This organization is essential for managing the complexity of a larger body.
