• B. They are responsible for storing genetic information exclusively.
• C. They serve as the main structural components and energy sources.
• D. They are solely involved in cell signaling processes.

Answer: (C)

Verified step by step guidance

1. Understand that organic molecules are diverse and play multiple roles in cells, not limited to a single function.
2. Recognize that organic molecules include carbohydrates, lipids, proteins, and nucleic acids, each with distinct roles.
3. Carbohydrates primarily serve as energy sources and structural components, such as glucose for energy and cellulose for structure.
4. Lipids are crucial for energy storage, forming cell membranes, and signaling, such as triglycerides for energy and phospholipids for membranes.
5. Proteins function as enzymes, structural components, and in signaling, while nucleic acids store and transmit genetic information, such as DNA and RNA.
