Solution

The correct option is B Radicle, Plumule
  • The epicotyl bearing shoot apex and leaf primordia are enclosed in a foliar structure called coleoptile. It protects the plumule during emergence from the soil.
  • The radicle is protected in a sheath called coleorhiza. It protects the radicle during its passage into the soil.
  • So, the correct answer is " radicle, plumule ".
