Explanation:
Compound (A) i.e., phenol and compound (D) i.e., a derivative of phenol cannot be considered as aromatic alcohol. As phenol is also known as, carbolic acid cannot be considered as aromatic alcohol.
Compound (B) and (C), -OH group is bonded to sp3 hybridised carbon which in turn is bonded to benzene ring.

$Pt$ $\mid H _{2}$ $(g,1 \,bar)$ $\left| H ^{+}( aq ) \| Cu ^{2+}( aq )\right| Cu ( s )$
is $0.31\, V$. The $pH$ of the acidic solution is found to be $3 ,$ whereas the concentration of $Cu ^{2+}$ is $10^{- x } \,M$. The value of $x$ is $.....$
(Given: $E _{ Cu ^{2+} / Cu }^{\ominus}=0.34 \,V$ and $\frac{2.303 RT }{ F }=0.06\, V$ )
$\therefore$ reactant $(A)$ is
