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

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

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

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

Explanation

To solve this problem, we need to match each item in column (a)-(d) with the correct description in column (i)-(iv). Let's analyze each one: $\\$ (a) CO(g) + H $_2$ (g): $\\$ This is known as synthesis gas or syngas, which is a mixture of carbon monoxide and hydrogen. $\\$ Thus, (a) matches with (iii) Synthesis gas. $\\$ (b) Temporary hardness of water:
