Solution

The correct option is A
the cotyledons remain underground

Epicotyl is the region of the embryonic axis between the point of attachment of cotyledons and plumule. If epicotyl elongates, the cotyledons remain underground (or on the ground if the seed is just on the ground) and germination is called as hypogeal.
