(b) The inquiry shall include all of the following:

(1) Whether the mother was married at the time of conception of the child or at any time thereafter.

(3) Whether the mother has received support payments or promises of support with respect to the child or in connection with the pregnancy.

(4) Whether any person has formally or informally acknowledged or declared possible parentage of the child.

(5) The names and whereabouts, if known, of every person presumed or alleged to be the parent of the child, and the efforts made to give notice of the proposed adoption to each person identified.

(c) The agency that completes the inquiry shall file a written report of the findings with the court.
