Aniline reacts with acetaldehyde to form

Which among the following is the strongest Bronsted base?

Given below are two statements:
Statement $I$: Aniline is less basic than acetamide.
Statement $II$: In aniline,the lone pair of electrons on nitrogen atom is delocalised over benzene ring due to resonance and hence less available to a proton.
Choose the most appropriate option:

$Y \xleftarrow[(ii)\,KOD, Br_2, \Delta]{(i)\,NH_3, \Delta} \text{Benzoic acid}$ $\xrightarrow[(ii)\,KOH, Br_2, \Delta]{(i)\,ND_3, \Delta} X$
What are $X$ and $Y$?

In the following reaction,the product $(A)$ is
