What Is the Consequence of a Transversion Mutation in Duplex

What is the consequence of a transversion mutation in duplex DNA?

A) A purine is replaced by a pyrimidine, and a pyrimidine is replaced by a purine.
B) A base pair is lost within the DNA of a gene, which causes a reading frameshift.
C) A purine is replaced by another purine, and a pyrimidine is replaced by another pyrimidine.
D) A base pair is added to the DNA within a gene, which causes a reading frameshift.
E) The sequence of the DNA remains the same since the change involves proteins.
