The correct option is (c) DDT
 
For explanation: The process of accumulation of certain pollutants (toxins) in the tissues of organisms whose concentration increases along the food chain is known as biomagnification or bioamplification. DDT, methylmercury, toxaphene are examples of such pollutants.
