There is a little difference in acid strength in the series H_3 PO_4, H_3 PO_3 and H_3 PO_2 because

Assertion (A): There is very little difference in acid strength of H_(3)PO_(4), H_(3)PO_(3) ,and H_(3)PO_(2) . Reason (R) : The hydrogens in these acids are not all bonded to oxygens. The electrone-grativities of P and H are almost the same.

Assertion: There is a very little difference in acidic strengths of H_(3)PO_(4),H_(3)PO_(3) and H_(3)PO_(2) . reason: Number of unprotonated oxygen (=O) responsible for increase of acidic strength due to inductive effective remains the same.

What should be the order of acidic strength in the series H_(3)PO_(4) , H_(3)PO_(3) , and H_(3)PO_(2) ?
