Answer 1

In our previous session, I was telling you that a mutagen is an external factor that can cause a mutation in the DNA of an organism, so factors such as UV light, heat, chemical substances, or also biological agents, if exposed to too much time, can be also mutagens for an organism. We can say then that the correct answer to this question is the third one: C. environmental factors that cause a mutation.
