Question

what is biology?
study of dna
study of rocks and soil
study of living things

Explanation:

Biology is defined as the scientific study of life and living organisms. The option "study of DNA" is too narrow (DNA is part of biology but not the whole field). "Study of rocks and soil" is geology. "Study of living things" matches the definition of biology.

Answer:

C. study of living things (assuming the third option is labeled C; if the original labels were different, adjust accordingly, but based on the selection, the correct option is the one stating "study of living things")
