Answer 2

Correct answer: B). Mutagens

Mutagens can be a chemical or physical agent that is known to change the nucleotide sequence of the DNA, and hence increases the frequency of mutation, which can cause cancer.

Mutagens may be carcinogenic but it is not always true, as some mutation is caused due to an error in DNA replication, and genetic recombination.
