The correct answer is (a) Grievous hurt.

Grievous hurt is an injury that causes serious damage to the body or health of the victim. It can include injuries such as broken bones, loss of teeth, and serious cuts. Hurt is an injury that is less serious than grievous hurt. It can include injuries such as bruises, cuts, and scrapes. Culpable homicide is the unlawful killing of a human being without malice aforethought. Attempt to hurt is an attempt to cause hurt to another person.

In the case of ‘A’ knocking down two teeth of ‘B’, ‘A’ has committed the offence of grievous hurt. This is because knocking down two teeth is a serious injury that can cause significant damage to the victim’s body and health.

The other options are incorrect because they do not accurately describe the severity of the injury that ‘A’ has caused to ‘B’.
