If Male A is on the birth certificate then that could have happened in one of two ways, either the parents were married or the parents signed a paternity affidavit acknowledging that Male A is the father of the child.
That being said, Male C can file a paternity action (actually so can the mother) and name Male A as a party to the lawsuit. Once paternity is established in Male C then Male C's name will be added to the birth certificate.
