Oxyacids of phosphorous and the starting materials for their preparation are given below. Oxyacid - Materials for preparation (a) H_3PO_2 - (i) Red P+ alkali (b) H_3PO_3 - (ii) P_4O_{10}+H_2O (c) H_3PO_4 - (iii) P_2O_3+H_2O (d) H_4P_2O_6 - (iv) White P + alkali Choose the correct answer from the codes given below

Correct Answer is : (a)−(iv);(b)−(iii);(c)−(ii);(d)−(i)

(a) - (iv) ; (b) - (iii) ; (c) - (ii) ; (d) - (i)

(a)-(i) ; (b)-(iii) ; (c)-(ii) ; (d)-(iv)

(a) - (iv) ; (b) - (iii) ; (c) - (i) ; (d) - (ii)

(a) - (ii) ; (b) - (iii) ; (c)-(i) ; (d) - (iv)

(a)-(iii) ; (b)-(i) ; (c) - (ii) ; (d) - (iv)
