Light-dependent repair corrects which of the following dna alterations?
a. methylation
b. thymine dimers
c. mismatched basepairing
d. hydroxylation
e. inversions

The correct answer will be option-B.

Explanation:

The light-dependent repair process is a process which repairs the pyrimidine dimers formed from the UV radiation. This process is also known as photo-reactivation which issued by the bacteria to repair the DNA.

The process requires specific enzymes like photolyase which binds to pyrimidine dimers usually thymine dimers formed and catalyze the reaction in the presence of visible light. The process returns the DNA state to its prior state before UV damage.

Thus, Option-B is the correct answer.
