Institutions accept and manage customer deposits in checking and savings accounts.

The correct answer is depository institutions.

Explanation:

We denominate Depository institution to financial entities that can legally receive and manage monetary deposits from costumers.

This institution serves as a way to keep a person's money securely, and thus achieve the physical security of the person who owns the money, since having a certain amount of money with himself can be dangerous.

A client will give his money to a depository institution, which also have several types of bank accounts, and when the client wishes, that money will be returned.

The depository Institution, while saving your money, can use it to make investments or to lend to other costumers.
