The answer is: A
Explanation
The correct option is A: grievous hurt.
According to section 320 of the Indian Penal Code, one of the kinds of hurt that is designated as grievous is "fracture or dislocation of a bone or tooth" . Therefore, if A has knocked down two teeth of B, A has caused grievous hurt to B. The other options are incorrect because:
- Simple hurt is defined as causing bodily pain, disease or infirmity, and does not include any specific injury .
- Culpable homicide is the act of causing death or such bodily injury as is likely to cause death, with intention or knowledge . Since A did not intend or know that knocking down B's teeth would cause B's death, A did not commit culpable homicide.
- Attempt to hurt is the act of doing something towards causing hurt, but failing to do so due to circumstances beyond one's control. Since A succeeded in causing hurt to B, A did not attempt to hurt B.
