Answer: B. 5-10 minutes

Bacteria are very tiny micro-organisms capable of splitting and multiplying at a very fast rate. Bacteria are known to double every four to five minutes. A single-celled bacteria cell can become two million in only a couple of hours. In just five seconds, bacteria contamination occurs as a food substance gets contaminated the moment it comes in contact with a bacterial environment.

All foods are prone to bacteria contamination but foods with high moisture or high starch content tend to be more susceptible to bacterial infection or contamination. Protein-rich foods are also very prone to bacterial infection.
