C Correct answer
Explanation

Potato Dextrose Agar (PDA) is a standard culture medium used to grow fungi and some bacteria in Petri dishes. It provides nutrients from potato infusion and dextrose (sugar). Glucose alone lacks other nutrients, while bone marrow and blood serum are not standard solid media for Petri dish cultures.
