D Correct answer
Explanation

Parasitism is the symbiotic relationship where the parasite benefits by taking nutrients or resources from the host, which is harmed in the process. Competition is not typically classified as a symbiotic relationship, and mutualism and commensalism do not involve harming an organism.
