Explanation / Answer

The answer is option (a) Campylobacter has specialized nutritional and atmospheric conditions for it to grow efficiently.

Campylobacter spp. are sensitive to environmental conditions such as temperature, availability of air and moisture, and the ability to survive in stress conditions.

They readily grow in a temperature range of 30 - 45 oC and not below 30oC, so it is unusual to find this spp. in retail poultry which is stored at room temperature (25oC).
