The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Tropism is a growth movement whose direction is determined by the direction of an environmental stimulus.
Step 2: Detailed Explanation:
After fertilization in groundnut, the ovary develops into a geotropic stalk called a "peg."
