please select the best answer from the choices provided

○ a
○ b
○ c
○ d

Explanation:

• Option a: Physical models (e.g., a model of a molecule) are often 3D, so this is true.
• Option b: Physical models represent objects/events (e.g., a globe for Earth), so this is true.
• Option c: Graphs are mathematical/conceptual models, not physical. Physical models are tangible (e.g., a model airplane), so this is false.
• Option d: Physical models can depict microscopic objects (e.g., a model of a cell), so this is true.

Answer:

C. Physical models are usually in the form of a graph.
