Explanation:

- Section 300 of the Indian Penal Code (IPC) defines what constitutes murder. It outlines the criteria and conditions under which culpable homicide becomes murder.

- Section 302 prescribes the punishment for murder, which is usually death or life imprisonment.

- Section 299 defines culpable homicide, which is a broader term and not always classified as murder. It involves causing death with the intent or knowledge that such acts can cause death.

- Option 4 is irrelevant as sections dealing with murder are included in 299, 300, and 302.
