Solution
The correct option is A During spore formation
In Rhizopus, when two compatible hyphae meet, it results in the formation of two zygosporangium.
At the tips, structures called gametangia are formed and the plasmogamy of two gametangia forms a zygospore. This zygospore is the only diploid cell in the entire lifecycle.
The same zygospore later undergoes meiosis to form haploid spores. So, meiosis occurs during haploid spores formation.
Zoospores are motile asexual spores.
