Answer : 3. "Bulimia "
Explanation :

(C) Bulimia

Bulimia nervosa is an eating disorder characterized by binge eating, which involves consuming large amounts of food in a short period of time, often with a lack of control. Individuals with bulimia then engage in compensatory behaviors, such as vomiting, excessive exercise, or fasting, to prevent weight gain. The person described in the question, who does not know when to stop eating, may be exhibiting characteristics of binge eating, which is a key feature of bulimia. Diabetes, anorexia, and hyperacidity are different health conditions and not typically associated with an inability to stop eating in the described manner.

Answer : 2. "Allethrins "
Explanation :

(B) Allethrins

Allethrins are active chemicals commonly used in mosquito repellents and insecticides to deter or eliminate mosquitoes. They belong to a class of synthetic pyrethroid insecticides, which are designed to mimic the insecticidal properties of pyrethrins, natural insecticides derived from chrysanthemum flowers. These chemicals are effective in repelling and killing mosquitoes and other insects. The other options (Benzene Hexachlorophene, Atropine, and 2-Isopropoxiphimyal) are not typically used for mosquito control.
