The relation between $(A)$ and $(B)$ is:
$CH_3-CONH_2 \xrightarrow{KOBr} (A)$
$CH_3-CONH_2 \xrightarrow{LiAlH_4} (B)$

Consider the following statements:
Statement-$I$: $CH_3NH_2$ is more basic than $NH_3$,but $C_6H_5NH_2$ is less basic than $NH_3$.
Statement-$II$: The order of basic strength of ethyl-substituted amines in the aqueous phase follows the order $(C_2H_5)_2NH > (C_2H_5)_3N > C_2H_5NH_2$.

The reaction of $N$-ethylcyclohexanamine with excess $CH_3I$ yields a product. Identify the product.

The decreasing order of the basic character of the following amines and ammonia is:

The order of basic strength among the following amines in benzene solution is
