• B. They can have specialized cells that perform different functions.
• C. They reproduce only by binary fission.
• D. They do not require energy to survive.

Answer: (B)

Verified step by step guidance

1. Understand the concept of multicellular organisms: Multicellular organisms are composed of many cells that work together, unlike unicellular organisms which consist of a single cell.
2. Recognize the advantage of specialization: Multicellular organisms can have specialized cells, meaning different types of cells perform specific functions (e.g., muscle cells for movement, nerve cells for signaling). This allows for greater efficiency and complexity in biological processes.
3. Eliminate incorrect options: Review the provided statements and identify inaccuracies. For example, multicellular organisms are not always smaller than unicellular organisms, and they do not reproduce only by binary fission (a method used by unicellular organisms).
4. Consider energy requirements: Multicellular organisms require energy to survive, just like unicellular organisms. The statement 'They do not require energy to survive' is incorrect.
5. Select the correct answer: The statement 'They can have specialized cells that perform different functions' accurately describes an advantage of multicellular organisms.
