    the correct value is 7 bits that required to represent.

    Explanation:

    Given dа ta:

    Voltage range is 0v to 5 v

    Accuracy / pm 50 mV = 0.05 V

    Meaning of 0.05 accuracy is 50 parts in 5000

    so ratio can be written in the form of 1 in 100

    so for representing 100 value 7 bits of information is required because 6 bits can represent 64 value only.

    hence the correct value is 7 bits
