Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of the origin of insecticide cartap hydrochloride.
Step 2: Detailed Explanation:
Cartap hydrochloride is a synthetic insecticide based on the natural compound nereistoxin.
Nereistoxin was first isolated from the marine annelid (Lumbriconereis heteropoda).
Actinomyces (A): Bacteria (source of antibiotics).
Bacteria (B): Not the source.
Protozoa (D): Not the source.
Thus, cartap hydrochloride was isolated from an annelid.
Step 3: Final Answer:
Thus, cartap hydrochloride was isolated from an annelid, which corresponds to option (C).
