Explanation:

- Correct Answer: Option:2, Mortgagee

- Mortgagor: The mortgagor is the borrower or the person who takes a loan by offering property as collateral. They transfer an interest in their property to the mortgagee.

- Mortgagee: The mortgagee is the lender or the entity to whom the property is transferred as security for the mortgage. They hold interest in the property until the loan is repaid.

- Co-owner: A co-owner shares ownership of a property with one or more persons. This is unrelated to the transfer aspect in this context.

- Executor: An executor is responsible for carrying out the terms of a will, managing the deceased person's estate, and does not relate to property transfer scenarios.
