The products $(A)$ and $(B)$ are formed by the following reaction sequence:
$1$. $\text{NH}_2\text{OH}$
$2$. $\text{H}^+, \Delta$
$3$. $\text{LiAlH}_4$
Identify the products $(A)$ and $(B)$.

The reaction shown in the image proceeds via which mechanism?

Given below are two statements: Statement $I$: The condensation reaction between $CH_{3} - CH = O$ and $H_{2}N - NH - C(=O) - NH_{2}$ under optimum pH will produce $CH_{3} - CH = N - N(H) - C(=O) - NH_{2}$. Statement $II$: The molecule, $Ph - CH(OH)(OCH_{3})$ will generate $Ph - CH = O$ in the presence of dilute acid. In the light of the above statements, choose the correct answer from the options given below:
