Explanation:

• Enriched media contains additional nutrients to support the growth of organisms with specific nutritional needs.
• Fastidious organisms have complex nutritional requirements, so enriched media helps their growth (second option is correct).
• Pathogens in low numbers need a nutrient - rich environment to grow, and enriched media provides that (third option is correct).
• Isolating microbes from complex mixtures is done by selective media, not enriched media (first option is incorrect).
• Preserving specimens during transport is done by transport media, not enriched media (fourth option is incorrect).

Answer:

B. the growth of fastidious organisms, C. growing pathogens that are present in low numbers
