• A. X-water, Y-wind, Z-gravity
• B. X-water, Y-wind, Z-explosions
• C. X-wind, Y-water, Z-animals
• D. X-wind, Y-animals, Z-water

Answer 1

The correct option is C X-wind, Y-water, Z-animals

Winged seeds such as those of drumstick and maple get blown
off with the wind to far away places. Some seeds are dispersed by water. These fruits or seeds usually develop floating
ability in the form of spongy or fibrous outer coat as in coconut. Some seeds are dispersed by animals, especially
spiny seeds with hooks which get attached to the bodies of animals and are carried to distant places. Examples are Xanthium and Urena.
