Solution

The correct option is D ${(C_{2} H_{5})}_{2} O$ and $N a B H_{4}$
An alkali metal hydride ( $N a H$ ) reacts with diborne in 'A' ( ${(C_{2} H_{5})}_{2} O$ ) to give a tetrahedral compound 'B' ( $N a B H_{4}$ ) which is extremely used as reducing agent in organic synthesis. The compounds 'A' and 'B' respectively are ${(C_{2} H_{5})}_{2} O$ and $N a B H_{4}$ .
$2 N a H + B_{2} H_{6} {(C_{2} H_{5})}_{2} O - ----- \to 2 N a B H_{4}$
