The computers that we use are digital whereas we live in an analog world which means that we have to translate analog data into digital data. What is the name of the circuit which helps us in this conversion?

Answer: Option B

Analog-to-digital conversion is an electronic process in which a continuously variable (analog) signal is changed, without altering its essential content, into a multi-level (digital) signal. The output of the ADC, in contrast, has defined levels or states.
