B. Only two
C. All three✓ Correct
D. None

Detailed Solution

✓ Correct Answer: Option C

The pea family is scientifically known as Fabaceae or Leguminosae, characterized by their distinctive legume fruits (pods) and often nitrogen-fixing capabilities. Let's examine each plant: 1.

Groundnut (Arachis hypogaea): Also known as peanut, it is a member of the Fabaceae family. 2. Horse-gram (Macrotyloma uniflorum): This is a pulse crop widely cultivated in tropical regions and belongs to the Fabaceae family.

3. Soybean (Glycine max): A globally important legume crop, native to East Asia, and is also a member of the Fabaceae family. Since all three plants—Groundnut, Horse-gram, and Soybean—are legumes, they all belong to the pea family (Fabaceae).

This question relates to basic botany and agricultural knowledge, relevant to both Environment & Ecology and General Science.
