To determine the correct answer, let's analyze each option in relation to what a latch represents in digital electronics.

1. Voltage Controller: This term typically refers to devices that regulate voltage levels, not applicable to the latching mechanism.

2. Astable Multivibrator: This type of multivibrator continuously oscillates between its high and low states and does not have a stable state. A latch does not fit this definition as it maintains a state indefinitely until changed.

3. Bistable Multivibrator: This is a device that has two stable states. A latch, which can hold a binary state (0 or 1) until it is changed by input, is a classic example of a bistable multivibrator.

4. Monostable Multivibrator: This multivibrator has one stable state and transitions to a temporary state in response to an input. Once the input pulse is removed, it returns to its stable state, which does not align with the functionality of a latch.

Final Answer

The correct answer is Bistable multivibrator. A latch can hold one of two states (0 or 1) and maintains that state until changed, making it a prime example of a bistable multivibrator.
