• B. $A\left(3\right),B\left(4\right),C\left(1\right),D\left(2\right)$
• C. $A\left(2\right),B\left(3\right),C\left(4\right),D\left(1\right)$
• D. $A\left(1\right),B\left(2\right),C\left(3\right),D\left(4\right)$

Answer 1

The correct option is A $A\left(4\right),B\left(3\right),C\left(2\right),D\left(1\right)$

$NaOH$ is caustic soda, used in soap industries for saponification

$N{a}_2{S}_2{O}_3$ (Sodium thiosulphate) is used as antichlor. Antichlor is used in bleaching of chlorine compounds.It is chemical that reacts with, any free chlorine or hypochlorite and neutralizes.

$NaCN$ (Sodium Cyanide) is used in soaps as a germicide.it kill the harmfull microbes.

$N{a}_{2}C{O}_3$ Sodium Carbonate is used in reduction of melting point of silica in the glass industries

Thus Correct option is A
