    A) \[2.0\]                                  

    B) \[2.5\]

    C) \[3.0\]                                  

    D) \[4.0\]

    Correct Answer: A

    Solution :

    We know\[p{{K}_{a}}=\log {{K}_{a}}\]i.e. higher the value of \[p{{K}_{a}}\], the weaker is the acid. Therefore, the acid with \[p{{K}_{a}}\] value 2 will be the strongest acid among these options.
