Biological macromolecules: function-structure alignment

Steps:

• Identify primary function of each molecule: cellulose provides structural support in plants via beta-linked glucose chains; collagen strengthens tissues with triple helices; triglycerides store energy as neutral fats.
• Examine proposed functions in options: A pairs cellulose with energy support (incorrect); B, C, D pair molecules with accurate functions.
• Assess symbols as indicators of structural feature matches to proposed function: X denotes mismatch, ✓ denotes match.
• Select option where symbols accurately reflect alignment: A shows all mismatches (X X X) for incorrect function pairing.

Not enough information to fully evaluate symbols without specified structural features (e.g., linearity, branching, hydrophobicity).

Final answer: Not enough information.
