Solution

The correct options are
A Compound A can be $N a_{2} C O_{3}$
B Compound D is $H B O_{2}$
C Compound E is $H_{2} B_{4} O_{7}$
$C a_{2} B_{6} O_{11} Colemanite + 2 N a_{2} C O_{3} (A) Δ - \to N a_{2} B_{4} O_{7} + 2 C a C O_{3} + 2 N a B O_{3}$

$H_{3} B O_{3} Δ, Strong - ----- \to B_{2} O_{3} (C)$
$H_{3} B O_{3} 100^{o} C - --- \to H B O_{2} (D)$
$H_{3} B O_{3} 160^{o} C - --- \to H_{2} B_{4} O_{7} (E)$
