The Correct Option is D

Solution and Explanation

The phrase is a biology definition, so the answer must be a word for an organism that lives on or inside another organism.

  1. Sycophant: This describes a person who flatters others to gain favour. It is a human trait, not a description of how an organism lives. Wrong.
  2. Bigot: This names a person who is intolerant of different opinions or beliefs. It has no connection to how one organism lives on another. Wrong.
  3. Proselyte: This is a person who has recently converted to a religion or belief. It is unrelated to biology. Wrong.
  4. Parasite: A parasite is an organism that lives in or on another organism, called the host, and draws nourishment from it. This matches the definition exactly. Correct.

Parasite is the only biological term among the choices, so option Parasite is correct.
