Solution

The correct options are
A $(X)$ is $B_{2} H_{6}$
B (Z) is known as inorganic graphite
C (Z) having structure similar to graphite
$B_{2} H_{6} + 2 N H_{3} \to B_{2} H_{6} .2 N H_{3}$
When the addition product is heated at $200^{\circ} C$ a volatile compound borazole or inorganic benzene is formed.
$3 B_{2} H_{6} .2 N H_{3} \to 2 B_{3} N_{3} H_{6} + 12 H_{2}$
$(X)$ is $B_{2} H_{6}$
Hence option A is correct.
