Answer : 1. " 4"
Explanation :
Actually, a nibble consists of 4 bits, not 3. In computing, a nibble is a unit of data that consists of 4 bits, which can represent 16 different values (2^4). Each nibble can be expressed as a single hexadecimal digit (0 to F, where F represents 15 in decimal) and is half of a byte, which consists of 8 bits. So, 4 bits make up one nibble.
