Correct Answer:
B. Hyphae
Explanation:
The correct answer is Option B: Hyphae.
In Rhizopus, commonly known as bread mold, the vegetative body is composed of a network of fine, tubular filaments called hyphae. These thread-like structures collectively form the mycelium. While some hyphae serve specialized roles—such as rhizoids for anchorage and nutrient absorption or sporangiophores that grow upright—the term hyphae generally describes the fundamental structural units of the fungus. At the tips of certain hyphae, swollen "blobs" called sporangia develop, which are responsible for producing spores for asexual reproduction. Unlike plants, these organisms do not possess true roots, and "filaments" is a more generic term rather than the specific biological name for these fungal structures.
