Correct option is C
A Voltage-Controlled Sample and Hold Circuit is a specialized electronic circuit precisely engineered for applications like analog-to-digital converters (ADCs). Its core function involves sampling an analog signal at a specific moment in time and holding that sampled value for the duration of the conversion process, which is critical for accurate signal processing. The timing is controlled by a precise control signal or voltage, ensuring the input to the ADC remains stable while the conversion takes place, thereby minimizing conversion errors.
