Correct answer: B. Hypocotyl

- B. Hypocotyl

- D. All (A), (B) and (C)
Explanation
Epigeal germination takes place due to the rapid growth of the hypocotyl. In this type of germination, the cotyledons are lifted above the soil surface, allowing the young shoot (epicotyl) and leaves to emerge. The hypocotyl elongates, pushing the cotyledons and the young shoot upward to reach the sunlight.
