aA-2; B-1; C-3; D- 4
bA-4; B-1; C-3; D-2
cA-2; B-3; C-1; D-4

✓ Correct answer: b) A-4; B-1; C-3; D-2
ExplanationA is matched with 4: Fruit develops from the ovary of the flower after fertilization.The ovary, which contains the ovules, transforms into the fruit as the seeds inside mature.This process is an essential part of the plant’s reproductive cycle.B is matched with 1: Seed originates from the ovule after fertilization.The ovule, located inside the ovary, contains the female gamete (egg cell).Once fertilized by the male gamete (pollen), the ovule develops into a seed, which contains the embryo and stored food for the new plant.C is matched with 3: Wood is produced from the stem of the plant.The stem, with its vascular tissues (xylem and phloem), supports the plant and transports nutrients.The xylem, which is a type of vascular tissue, forms the wood, providing structural support and helping in water transport.D is matched with 2: Starch is primarily produced in the leaf.During photosynthesis leaves use sunlight, water, and carbon dioxide to produce glucose.Some of this glucose is converted into starch, a storage form of sugar, and is stored in the chloroplasts of the leaf.401
