Rhizopus stolonifer comes under the devision Zygomycota, they reproduce sexually when adjancent hyphae of two different mating types release chemical signals called pheromones, which cause them to grow toward each other.

Solution
The answer is "a". Rhizopus stolonifer comes under the devision Zygomycota, they reproduce
sexually when adjancent hyphae of two different mating types release chemical signals called
pheromones, which cause them to grow toward each other. These hyphae produce gametangia, in
which the nuclei replicate without cell division, resulting in multiple haploid nuclei in both
gametangia. The two gametangia then fuse to form a zygosporangium with many haploid nuclei
from each mating cell. Pairs of haploid nuclei then form multiple diploid nuclei within a
unicellular zygospore. Zygospore is a dormnant form. The answer is "d". The two gametangia
(male and female) then fuse to form a zygosporangium with multinuclei. Only the zygospore
undergo meiosis before releasing the spores.
