Matching functions to animal cell structures Steps:

• Function 3 synthesizes polypeptides on rough ER, matching V (membranes surrounding enclosed inner cavity).
• Function 1 involves centrioles producing microtubules for spindle formation, matching W (centriole appearance, non-membrane bound structures).
• Function 2 involves centrosome synthesizing microtubules for spindle, matching Z (non-membrane bound spherical structures organizing microtubules).
• Eliminate mismatches by confirming only C aligns all three correctly.

Why C is correct:

• Rough ER (V) hosts ribosome-mediated polypeptide synthesis; centrioles (W) produce spindle microtubules; centrosome (Z) synthesizes them, per cell biology definitions.

Why the others are wrong:

• A: Assigns 3 to Z (nucleus, not for polypeptides).
• B: Assigns 1 to Y (Golgi-like stack, not for microtubules); 3 to V correct but others fail.
• D: Assigns 3 to W (centriole, not for polypeptides).

Final answer: C
