Which of the following is not true about acetophenone?

Which of the following compounds does not react with Tollen's reagent?

Given below are two statements:
Statement $I$ : Acidity of $\alpha$-hydrogens of aldehydes and ketones is responsible for Aldol reaction.
Statement $II$ : Reaction between benzaldehyde and ethanal will $NOT$ give Cross-$Aldol$ product.
In the light of above statements,choose the most appropriate answer from the options given below.

Ketone reacts with $NH_2OH$ to give oxime. The reaction is as follows:
$R_2C=O + H_2N-OH \rightarrow R_2C=N-OH + H_2O$
The total number of organic products (ketoxime) formed when the simplest ketone and its next higher homologue react with $NH_2OH$,is:

The major product $(Z)$ of the following chemical reaction is

$CH_3-CO-OC_2H_5 \xrightarrow{H_2N-NH_2} X$; $CH_3-CO-C_2H_5 \xrightarrow{H_2N-NH_2} Y$. $X$ and $Y$ are:
