Think about the label for someone who studies living things. A biologist is a scientist who studies life in all its forms, from cells to ecosystems. The prefix 'bio-' means life and the suffix '-logy' means study, so biology is the study of life and a biologist is the person who does that work. The other options aren’t about studying life: one is the name of a snake, another refers to someone who carries messages, and the last means “in a technical way,” which isn’t a person. Because the question asks for the name of the scientist who studies living things, biologist is the best fit.
