Final answer:
Sabouraud dextrose agar CC is selective for non-saprophytic fungi, particularly broad-spectrum Dermatophytic fungi.
Step-by-step explanation:
Sabouraud dextrose agar (SDA) or Sabouraud dextrose agar CC is a type of growth media that is selective for fungi, particularly for broad-spectrum Dermatophytic fungi, which are a type of pathogenic fungi that affects the skin. This medium has a low pH that inhibits bacterial growth, making it an excellent choice for isolating and cultivating fungal species from samples that may also contain bacteria. It is not designed to select for gram-positive bacteria, gram-negative bacteria, mycobacteria, or viruses. Given the options provided in the student's question, the correct answer is (b) non-saprophytic fungi, referring to fungi that require specific nutrient conditions that SDA provides.
