The order of stability of cyclohexane conformations is :

When a substance $A$ reacts with water, it produces a combustible gas $B$ and a solution of substance $C$ in water. $D$ reacts with this solution $C$ and produces the same gas $B$ on warming. $D$ can also produce gas $B$ on reaction with dilute $H_{2}S{O}_4$. $A$ imparts a deep golden yellow colour to smokeless flame. $A,B,C$ and $D$ respectively are
