Explanation:

• For option A: An organ system is a group of organs working together. If the diagram (likely of the nervous system part like spinal cord with related structures) represents a system of organs (or structures) working together, it could be an organ system.
• For option B: An organism is a whole living being (like a human, animal), a diagram of just spinal - related structures won't represent an entire organism.
• For option C: Gray matter is nervous tissue (part of the nervous system's tissue composition).
• For option D: The spinal cord is an organ (made of different tissues), not an organ system (an organ system has multiple organs). So the correct statements are A and C.

Answer:

A. The diagram as a whole represents an organ system, C. Gray matter is tissue
