Among the zygomycetes, which lacks rhizoids?

Explanation:
Rhizoids are root-like hyphae that anchor the mold to the substrate and help with nutrient uptake. In zygomycetes, whether rhizoids are formed at the base of the sporangiophores helps distinguish genera. Mucor typically does not develop rhizoids, so you won’t see those anchor-like structures attached to the surface. The other genera in this group commonly show rhizoids at the point where the sporangiophores emerge, helping anchor and organize growth. Therefore, a zygomycete that lacks rhizoids aligns with Mucor, making it the best match.
