Answer:

B.

Step-by-step explanation:

Causes mutations in DNA.

The signature mutation caused by ultraviolet light is a CC to TT mutation, caused when a CC dimer is mispaired with two adenine bases during replication. Because of these mutations, the connection between ultraviolet damage to DNA and cancer is quite clear.
