Explanation:

To solve this, we analyze each option:

• Option 1: General - purpose media (like nutrient agar) support a wide variety of microbes.
• Option 2: Synthetic (chemically definable) media have known chemical compositions, but general - purpose media are often complex (e.g., contain extracts), so this is incorrect.
• Option 3: General - purpose media have multiple nutrients (synthetic and non - synthetic), so this is incorrect.

Answer:

A. allowing the growth of a broad range of microbes
