  • B
    Food stored in the stem.
  • C
    A stem covered with scales.
  • D
    A stem that grows horizontal to the earth.
✓

Answer

Correct option: A.
Vegetative propagation.
These plants produce stems modified to store energy and preserve a location of potential growth to survive a cold or dry period which normally is a period of inactive growth, and when that period is over the plants resume new growth from the underground stems.
$[4]$ Being underground protects the stems from the elements during the dormancy period, such as freezing and thawing in winter or extreme heat and drought in summer or fire.
