    A)    

    B)            

    C)          

    D)

    Correct Answer: B

    Solution :

    The compound in option (B) will not exist in zwitter ionic form at \[\text{pH=7}\] as N is in the form of amide group and not in the form of amine. Hence, at \[\text{pH=7}\], amide N will not be protonated.
