★ Correct answer is option 3

★ Molecular mass of orthophosphoric acid (H3PO4) is 98g

★ since it is tribasic in nature , its equivalent weight is 98/3

★ Phosphoric acid (H3PO3)

since, it is dibasic in nature ..its equivalent weight is 82/2 (molecular weight 82g)

Therefore, correct answer is Option 3

✔️1/3 and 1/2 of their respective atomic weight.
