Explanation:

Let’s break down these options:

- Contingent bequest: This is a gift that only takes effect if a certain event happens. For example, “I leave $5,000 to Sam if he graduates college.” If the event doesn’t occur, the gift doesn’t happen. But just because the event is uncertain doesn’t mean the bequest is automatically void.

- Bequest made to the child in womb born within six months: This is called a bequest to an unborn child, but as long as the child is born alive within a certain legal timeframe, it’s not void. Law usually allows this.

- Alternative bequest: Here’s when the will says, “If A doesn’t get it, give it to B.” The alternate option kicks in if the main one fails. So, that’s not void either.

- None of these: This covers choices that don’t fit the definition.

A void bequest is one that is not legally valid from the beginning, maybe because the recipient doesn’t exist or can’t be located, or the object isn’t clear in the will.

The right answer is:

Option:4, None of these
