The reagent used in the Wolff-Kishner reduction is

How many aldol products (excluding stereoisomers) are obtained in the given reaction?
$CH_3-CH_2-CHO + C_6H_5CHO \xrightarrow[0-5 \ ^{\circ}C]{OH^{\ominus}} ?$

The reagents $A$,$B$ and $C$ respectively are:

What is the product obtained in the reaction?
$CH_3-CH=CH-CH_2-CHO \xrightarrow[(ii) H_3O^{+}]{(i) LiAlH_4} \text{product}$

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.

The reaction of chloroform with acetone gives ...................
