Concept:Hypogeal germination is a type of seed germination in which the cotyledons remain below the soil surface.
Explanation:In hypogeal germination, the epicotyl elongates and pushes the plumule above the ground, while the cotyledons stay underground.
Common examples include maize, which is a monocot, and groundnut, which is a dicot.
Both plants therefore show hypogeal germination.
Because both options B and C are correct, the question is ambiguous as written.
Answer:B. groundnut and C. maize both show hypogeal germination.
