Step 1: Understanding hypogeal germination.
In hypogeal germination, the cotyledons remain below the soil surface while the plumule grows upward. This protects the cotyledons from environmental damage. Step 2: Analyzing the options. (A) Pea: Incorrect. Pea shows hypogeal germination. (B) Tamarind: Correct. Tamarind shows epigeal germination, not hypogeal. (C) Groundnut: Incorrect. Groundnut shows hypogeal germination. (D) Gram: Incorrect. Gram also shows hypogeal germination. Step 3: Conclusion.
The correct answer is (B) Tamarind because it does not show hypogeal germination.
