Penicillium produces

Asexual reproduction begins with the formation of asexual motile spores called conidia, which are born on the erect, aerial hyphae called conidiophores. The conidiophores branch multiple times and finally terminate into cylindrical bodies called sterigma. At the time of conidium formation, the nucleus of sterigma divides by mitotic division into two. The terminal portion of sterigma gets separated with one nucleus and is called conidium. When it is fully grown another conidium is formed below the first conidium in succession at the end of sterigma. The spores thus formed are mitospores, which germinate to form genetically identical saprophyte.

In sexual reproduction, the spores or conidium are formed by meiosis from the diploid parent zygote. Ascogonium, a female sex organ and Antheridium, a male sex organ arise on adjacent branches and fuse to form meiospores.

Zoospores are spores with flagella. They are motile spores. They are not produced by Penicillium.

Thus, the correct answer is option D.
