The answer is b. They both lay amniotic eggs. Both birds and reptiles belong to a clade of vertebrates, Amniotes, which lay amniotic eggs. Mammals also belong to Amniotes. Amniotic eggs can remain within the mother after fertilization or can be laid on land. On the other side, anamniotic eggs are usually laid in the water.
