Explanation:

- If two groups, both armed with deadly weapons, deliberately get into an unlawful fight and someone dies, the law considers their intention.

- Such cases usually fall under "murder" because both sides knowingly risk lethal harm, not just accidental or unplanned violence.

- Option 1: It is homicide – Homicide means any killing of a person by another, whether justified or not, so it’s a broad term.

- Option 2: It is murder – This is correct. Since both groups knowingly took part in unlawful fighting with deadly weapons, the element of intention or knowledge (needed for murder) is present.

- Option 3: It is not murder – Not true. Their deliberate violent actions make them culpable for murder, not mere accident.

- Option 4: None of the above – Not correct as one answer fits.
