C Correct answer
Explanation
  • Cactus develops long roots to go deep into the ground to get water. - Chlorophyll only helps in photosynthesis; it does not help in conservation of water. -  Waxy coating around the plant body reduces water loss.
    • The leaves of cactus are reduced to spikes resulting less number of stomata and less transpiration.
