b: air has mass, but not inertia.
c: air is not affected by human movement.
d: none of these statements are true.

please select the best answer from the choices provided.
○ a
○ b
○ c
○ d

Explanation:

• Option A: Air does provide resistance (e.g., air resistance when moving objects). So A is false.
• Option B: Any object with mass has inertia, and air has mass, so it has inertia. B is false.
• Option C: Human movement (like walking, running) displaces air, so air is affected. C is false.
• Since A, B, C are false, the correct answer is D.

Answer:

D. None of these statements are true.
