• A. Ascus of Penicillium
• B. Sporangium of Rhizopus

• D. None of the above

Answer 1

The correct option is B Sporangium of Rhizopus

Columella is present on the tip of long stalk known as sporangiophore, present in the Rhizopus. It supports the Sporangium which has asexual spores. It helps nutrient exchange between the active protoplasm below and the developing spores inside the upper portion of the sporangial head. Sporangiophores arise among distinctive, root-like rhizoids.

So, the correct answer is option B.
