C Correct answer
Explanation

Induced mutation on the molecular level can be caused by ultraviolet radiation. Two nucleotide bases in DNA that is cytosine and thymine are most vulnerable to radiation that can change their properties. UV light can induce adjacent pyrimidine bases in a DNA strand to become covalently joined as a pyrimidine dimer.
