lf 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 answers are to the base 2, and [log n] means the floor of log n)

• A. [log(n)] + 1 bits
• B. [log (n-1)]+1 bits
• C. [log (n+1)] + 1 bits
• D. None of the above
