The correct answer is the Ground Fault Circuit Interrupter (GFCI). This component is specifically designed to protect against minor electrical leaks by quickly shutting off power to the circuit when it detects a discrepancy in the flow of electricity. The purpose of a GFCI is to prevent electric shock and potential damage from electrical fires that can result from ground faults.

The other options are incorrect:

- Electrical Main Disconnect Switch (A) is a component used to completely disconnect power from a property, typically for maintenance or safety purposes.

- Grounded Outlet (C) refers to an outlet that has a ground wire for safety purposes but does not actively protect against minor electrical leaks like a GFCI.

- Electrical Leakage Circuit Breaker (D) is not a standard component in electrical systems and is not specifically designed to protect against minor electrical leaks like a GFCI.
