D Correct answer
Explanation

Parasites are organisms that live on or in another organism (the host) and feed upon it, benefiting at the host's expense. They do not utilize sunlight (that's autotrophs like plants), do not use inorganic compounds for energy (that's chemoautotrophs), and do not synthesize their own food (that's the definition of autotrophy).
