Explanation:

Let’s make this simple and clear:

- Section 494 of the Indian Penal Code (IPC) deals with marrying again during the lifetime of a husband or wife. If you marry again while your spouse is still alive and your first marriage hasn’t been legally dissolved, that’s bigamy, and it’s punishable under this section.

- Section 493 is about a man deceiving a woman into a belief of lawful marriage and then cohabiting with her—not quite the same thing.

- Section 495 is also about bigamy, but with the added twist of hiding the first marriage from your new spouse—a bit sneakier, and it carries extra punishment.

- Section 496 is for someone who goes through a marriage ceremony with fraudulent intent with someone who isn’t—and doesn’t believe themselves to be—lawfully married. It’s about deceit, not just marriage.

The answer is Option 2: 494.
