b. be indiscriminant about which females they mate with.
c. mate with as many females as possible.
d. compete to mate with choosy females.
</span>
The answer is a: be choosy about which females they mate with. 
This is because the male would in this case be investing a lot of energy in parenting its young, and would therefore adopt a strategy of mating with one or very few females. It therefore makes sense that the male would be choosy in regards to its mate.
