Explanation:

- The statement refers to something that acts as a security for the payment of any money.

- Option 1: Charge – A charge is a legal right over assets, typically to secure the repayment of a debt. It doesn’t transfer ownership, but gives the lender some control over the asset if the borrower defaults.

- Option 2: Mortgage – A mortgage is a type of charge but specifically relates to immovable property. It also secures payment of money but is more specific than the broader term 'charge.'

- Option 3: Exchange – Exchange is the act of trading one thing for another, not typically used to secure payment.

- Option 4: Lease – A lease is a legal agreement where one party rents from another. It’s not security for money repayment.

- The most correct and general answer here is Option 1: Charge.
