Which letter from the fungus diagram represents the hyphae?

C

Explanation:

Hyphae is the vegetative growth of fungi. It is long and filamentous in nature and is analogous to the rhizoids of runner plants. A network of many crisscrossing hyphae is called mycelium, When a hyphae branches vertically upwards to give rise to a sporangium, it is called a sporangiophore (such as the case in the attached diagram).
