Which one of the following aldehydes will not form an aldol when treated with $dil. \, NaOH$?

Which of the following statements regarding the chemical properties of acetophenone is incorrect?
$I.$ It is reduced to methyl phenyl carbinol by sodium and ethanol.
$II.$ It is oxidized to benzoic acid with acidic $KMnO_4$.
$III.$ It does not undergo electrophilic substitution reactions (like nitration at the $m$-position).
$IV.$ It does not give the iodoform test with iodine and alkali.

$CH_3-C(O)-CH_2-CH_2-CH_2-CH_2-CHO \xrightarrow{HO^{-} / \Delta} (A) (73\%)$
Product $(A)$ is

Consider the following sequence of reactions:
$2-\text{benzylbenzoic acid}$ $\xrightarrow[2. \text{anhyd. } AlCl_3]{1. SOCl_2} A$ $\xrightarrow{Zn-Hg, \text{Conc. } HCl} B$
The end product $(B)$ is:

Treatment of propionaldehyde with dil. $NaOH$ gives:

Match the compounds in Column-$I$ with their respective intermolecular attraction forces in Column-$II$.

Column-$I$ (Compound)	Column-$II$ (Attraction Forces)
$A$. Aldehyde	$i$. Intermolecular hydrogen bond formed in $ROH$ between $O^{\delta -}$ of one molecule and $H^{\delta +}$ of another molecule.
$B$. Ketone	$ii$. Dipole-dipole forces between $C^{\delta +}$ of one molecule and $O^{\delta -}$ of another molecule.
$C$. Alcohol	$iii$. van der Waals forces
$D$. Alkane	$iv$. Ionic forces
