Explanation:

- Section 302 of the Indian Penal Code (IPC) prescribes punishment for murder.

- Section 149 of the IPC revolves around unlawful assembly. It holds every member guilty of an offense if any member commits it in prosecution of the common object.

- Acquittal of two persons means only four individuals remain.

- For a charge under Section 149, at least five members are needed to form an unlawful assembly.

- Fewer than five members cannot be convicted under Section 149, making it inapplicable in this case.

- Therefore, the remaining four cannot be convicted under Section 149.

Option 2 - Sec. 149 is the correct answer.
