  1. Epigeal germination

  2. Hypogeal germination

  3. Both A and B

  4. None of the above

Show answer
Correct Option: B
Explanation:

In hypogeal germination, the cotyledons do not come out of the soil surface. In such seeds, the epicotyl (i.e., part of the embryonic axis between plumule and cotyledons) elongates pushing the plumule out of the soil. All monocotyledons show hypogeal germination.

So the correct option is 'Hypogeal germination'.
