The second alternative is correct (B).
Banks provide loans to finance the needs of economic agents (people or companies). These needs can be personal or business. For example, a person hires a loan to buy a home. A businessman hires a loan to increase the size of his factory.
The loan is secured by a contract where the contracting party agrees to repay the amount plus interest, which is the bank's profit. This is the way to get the financing done, after all the bank would not have the incentive to lend if it was not to recover the total plus interest.
