Step 1: Read the task. We match four biomolecules with their main role. Let us identify each one. Step 2: Match starch (A). Starch is the storage carbohydrate of plants, so it pairs with the storage role II. Thus A goes to II. Step 3: Match antibody (B). Antibodies are defence proteins made by the immune system, so B pairs with defence against infection I. Thus B goes to I. Step 4: Match Concanavalin A (C). Concanavalin A is a lectin, a sugar-binding protein, so C goes to IV. Step 5: Match GLUT-4 (D). GLUT-4 is a glucose transporter protein, so D goes to III. Step 6: Assemble and conclude. The full match is A-II, B-I, C-IV, D-III, which is option 1. \[ \boxed{\text{A-II, B-I, C-IV, D-III}} \]
