Refer to the Figure Below, and Then Answer the Question

Refer to the figure below, and then answer the question that follows.

-A mistake is made during DNA replication,so there is incorrect base pairing in the DNA.Depending on how the replication repair mechanism fixes this problem,a point mutation may or may not result.What might the replication repair mechanism do,and would it result in a point mutation?

A) The repair mechanism might replace the T with a C, which would result in a point mutation.
B) The repair mechanism might replace the G with an A, which would result in a point mutation.
C) The repair mechanism might replace the G with a C, which would result in a point mutation.
D) The repair mechanism might replace the T with a G, which would not result in a point mutation.
