Question

Match the column I with column II and mark the appropriate choice .

	Column I		Column II
A	Clark's method	i	$N{a}_6{P}_6{O}_{18}$
B	Calgon's method	ii	$NaAlSi{O}_4$
C	Ion-exchange method	iii	$RS{O}_{3}H$
D	Synthetic resins method	iv	$Ca(OH{)}_2$

• A. $\left(A\right)\to \left(i\right),\left(B\right)\to \left(iiI\right),\left(C\right)\to \left(iv\right),\left(D\right)\to \left(ii\right)$
• B. $\left(A\right)\to \left(ii\right),\left(B\right)\to \left(iii\right),\left(C\right)\to \left(iv\right),\left(D\right)\to \left(i\right)$
• C. $\left(A\right)\to \left(iii\right),\left(B\right)\to \left(ii\right),\left(C\right)\to \left(i\right),\left(D\right)\to \left(iv\right)$
• D. $\left(A\right)\to \left(iv\right),\left(B\right)\to \left(i\right),\left(C\right)\to \left(ii\right),\left(D\right)\to \left(iii\right)$

Answer 1

The correct option is D $\left(A\right)\to \left(iv\right),\left(B\right)\to \left(i\right),\left(C\right)\to \left(ii\right),\left(D\right)\to \left(iii\right)$
