Which choice is an example of a symbiotic association of a protozoan with its mode of association? . a plasmodium in the blood cells of humans in the digestions of food material stored within. b. trypanosoma lives in the intestine and in absorption of nutrients . c. trichonympha lives in the gut of termites and digests cellulose eaten by the termite.

The correct answer will be option-C

Explanation:

Termites are the insects which feed on the wood. Termites are unable to digest the food material that is cellulose on their own which is mediated by the single-celled organism called Trichonympha.  

Trichonympha is the protozoans which live inside the guts of these termites s endosymbionts as these protozoans help digest the cellulose by producing cellulases and in return favored by the termites receiving the shelter and the food.
