Explanation:

Let’s break it down:

- Section 493: Deals with a man deceitfully causing a woman to believe she is lawfully married to him. Not about marrying again while spouse is alive.

- Section 494: This one’s the key. It punishes marrying again during the lifetime of a husband or wife—basically, bigamy.

- Section 495: This section is about hiding a former marriage when marrying again. So it’s about concealment, not the act of remarrying itself.

- Section 496: Covers marrying fraudulently to deceive someone, not standard bigamy.

In short: Section 494 nails the offense. If someone marries again while their spouse is still alive, this is the section that applies.
