Ethyl acetate reacts with $CH_3MgBr$ to form

In the following reaction,'$A$' is

The best reagent to carry out the following conversion is:
$3$-hydroxyethylcyclopentane-$1$-carbaldehyde $\rightarrow$ $1$-ethyl-$3$-methylcyclopentane (with a hydroxy group on the ethyl side chain).
(Note: The image shows the reduction of an aldehyde group $-CHO$ to a methyl group $-CH_3$ while keeping the secondary alcohol $-CH(OH)CH_3$ intact.)

The product $(A)$ of the reaction is:

Statement-$I$ :- Acetaldehyde and acetone can be distinguished by Tollen's reagent.
Statement-$II$ :- Aromatic aldehyde does not give Fehling test.

The reagent used in the Wolff-Kishner reduction is
