Correct Option: C

The kilobit is a multiple of the unit bit for digital information or computer storage. The prefix kilo (symbol k) is defined in the International System of Units (SI) as a multiplier of 103 (1 thousand), and therefore, 1 kilobit = 103 bits = 1000bits. However, computers are binary or base 2, as in ones and zeros. So instead of counting by tens, they count by 2s. So instead of 1,10,100,1000 it is 1,2,4,8,16,32,64,128,256, 512, 1024.
