If a variable can take only integral values from 0 to n, where n is an integer, then the variable can be represented as a bit-field whose width is ( the log in the answersare to the base 2, and [log n] means the floor of logn )

A

$$[\log(n)]$$ + 1 bits

B

$$[\log(n - 1)]$$ + 1 bits

C

$$[\log(n + 1)]$$ + 1 bits

D

None of the above
