Correct answer
DH2SO3 is the reducing agent because it undergoes oxidation

Step-by-step explanation

  Identify oxidation states of all elements in Redox Reaction

H2SO+43+Sn4++H2O(l)→Sn2++HSO4- +6 +3H+

S is changing the oxidation state from (+4) to (+6). i.e H2SO3 is a Reducing agent because it undergoes oxidation.
