Solution
The correct option is A Zoospores Zoospores are motile spores, usually formed in Algae and other plant forms. In fungi zoospores are absent. Rhizopus belong to Phycomycetes, where the hyphae are filamentous, coenocytic and reproduce asexually by formation of sporangiospores in the sporangia. Sporangia are club like structures formed at the tip of erect hyphae. The entire content of the hyphae moves into the buldged tip and is sealed or separated by the rest of the hyphae by a sterile region called the columella
