Solution

The correct option is A $(i), (i i), (i i i), (v)$
The metal bicarbonates (i) $L i H {C O}_{3}$ (ii) ${C a (H C O}_{3})_{2}$ (iii) ${Z n (H C O}_{3})_{2}$ (v) ${A g H C O}_{3}$ does not exist in solid state. However the metal bicarbonate (iv) ${N a H C O}_{3}$ exist in solid state. The alkali metals are highly electropositive, these are the only elements which form stable solid bicarbonates. However lithium due to its less electropositive nature, does not form solid bicarbonate.
