Answer:

The correct answer is option c. "DNA photolyase".

Explanation:

DNA photolyase is an unique DNA repair enzyme that harvests the light energy to repair the lesions produced by the exposure of ultraviolet light. DNA photolyase is light dependent and there are two types: one for repairing cyclobutane pyrimidine dimers and the other for pyrimidine-(6-4)-pyrimidone photoproducts.
