Explanation:

Here’s how it breaks down:

- Option 1: Housename

This means the name given to a house, a family title, or ancestry marker.

Often used in Kerala or among some South Indian communities.

People may be called by their housename as an identifier.

- Option 2: Internal marriage

This idea is about marriage within a specific group—sometimes a community or clan.

But ‘intipean’ isn’t used for this meaning, so this one’s out.

- Option 3: Unmarried girl

Describes a girl who hasn’t married yet.

Again, ‘intipean’ doesn’t refer to this.

- Option 4: Religious ceremony

Refers to formal acts or rituals.

‘Intipean’ isn't a term used for this either.

So, the right answer?

Option 1: Housename
