The Correct Option is C

Solution and Explanation

Step 1: Understanding the Concept:
Plant commercial fibers are classified into seed hair fibers, bast (stem phloem) fibers, leaf fibers, and fruit mesocarp fibers.

Step 2: Detailed Explanation:

Commercial coir fiber (coir yarn and geotextiles) is extracted from the thick fibrous fibrous mesocarp (husk) of the drupe fruit of the coconut palm (Cocos nucifera L., family Arecaceae) through water retting and mechanical decortication.
Sisal is a leaf fiber (Agave sisalana), Cotton is a seed hair (Gossypium), and Kapok is a fruit pod endocarp hair (Ceiba pentandra).

Step 3: Final Answer:

Hence, commercial coir is obtained from Coconut.
