Solution

The correct option is A Both (R) and (A) are true and reason is the. correct explanation of assertion
On comparing acidic strength in oxyacids the larger the oxidation state of the central atom the stronger the acid and if the oxidation is same than the electronegative the central atom is stronger the acidic strength.
