(c) before the birth of the child, he and the mother of the child married each other in apparent compliance with law, even if the attempted marriage is or could be declared invalid, and the child is born during the invalid marriage or within 300 days after its termination by death, annulment, declaration of invalidity, or divorce or after a decree of separation; or

(d) after the birth of the child, he and the mother of the child married each other in apparent compliance with law, whether or not the marriage is, or could be declared, invalid, he voluntarily asserted his paternity of the child, and there is no other presumptive father of the child, and:
