The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of phytoalexins and their source plants.
Step 2: Detailed Explanation:
Rishitin (B) is a phytoalexin produced by potato (Solanum tuberosum).
It is produced in response to infection by Phytophthora infestans (late blight).
Other phytoalexins:
- Cotton (A): Gossypol.
- Pepper (C): Capsidiol.
- Pea (D): Pisatin.
Thus, rishitin is produced by potato.
Step 3: Final Answer:
Thus, rishitin is a phytoalexin produced by potato, which corresponds to option (B).
