+ AnswerE

+ ExplanationConsider on the expression:
5||2|1
=5|| (2|1)  //Bitwise or has higher precedence
=5||3
=1

Now, value of each case expression:
3&2 = 2
-~11 = -(-12) =12
6-3<<2 = 3 <<2=  12 5>=5 = 1

case -~11 and case 6-3<<2 have same constant expression i.e. case 12
In c duplicate case is not possible.
