The correct answer is: B.To maintain homeostasis and coordinate body systems.

Explanation:

In multicellular organisms, cells need to communicate to ensure that the body functions as a coordinated whole. Communication between cells is essential for:

1.Maintaining homeostasis: This allows cells to respond to changes in the internal and external environment, ensuring a stable internal state (e.g., temperature regulation, blood sugar levels, etc.).

2.Coordinating body systems: Different cells and organs must work together for complex processes like digestion, immune responses, and growth. Cell signaling enables this coordination.
