- As we have learnt:

  • Zoospores are motile and flagellated spores produced in zoosporangia. These generally lack a cell wall. These are seen in Phycomycetes and many algae.
  • Conidia are formed in ascomycetes fungi. These are non-motile spores that can be formed singly or in a chain on special branches called conidiophores. These are produced exogenously.
  • Oidia are formed when the hyphae break and each fragment forms a spore. These can multiply by budding.

Hence, only statements b & d are correct.
