You're on a roll — a) A: Tridax fruit* (or Dandelion fruit) B: Tomato fruit* (or Guava fruit, or any fleshy fruit with small seeds) C: Coconut fruit* b) I: Fibrous husk (mesocarp)* - Provides buoyancy for water dispersal and protects the inner parts. II: Hard shell (endocarp)* - Provides strong protection for the seed (embryo and endosperm) inside. IV: Seed (endosperm/embryo)* - Contains the food reserves (coconut meat and water) for the developing embryo and the embryo itself, which will grow into a new plant. c) A (Tridax fruit - Wind dispersal): It is lightweight* to be easily carried by wind. It has a pappus (feathery hairs)* that acts like a parachute, increasing its surface area and allowing it to float in the air. B (Tomato fruit - Animal dispersal): It has a fleshy and succulent pericarp* that is edible and attracts animals. It is often brightly colored* to attract animals visually. C (Coconut fruit - Water dispersal): It has a fibrous husk (mesocarp)* with air spaces, making it buoyant to float on water. It has a waterproof outer layer (exocarp)* to prevent water from entering and damaging the seed during long periods of floating. Drop the next question.
