Answer:

The correct answer is a. Bacillus cereus

Explanation:

Bacillus cereus is the bacteria that causes food poisoning in the form of acute intoxication. It release toxins in the food and spread through previously cooked food, fried rice, vegetables, etc.

It is able to cause two gastrointestinal illnesses like diarrhoeal syndrome and an emetic (vomiting) syndrome. The signs and symptoms the enterotoxin appear within 24 hours after ingestion of the toxin.

So as here the boy is getting nausea, multiple episodes of vomiting and three loose bowel movements after eating leftover rice stored in the refrigerator the night before therefore in this situation the most likely causative agent is a. Bacillus cereus.
