Q. Which of the following is correct method to convert $p$ -toluidine to $p$ -toluic acid?

Diazotisation, $C u CN$ , $H_{2} / P d$

$C H C l_{3} / N a O H$ , $K CN$ , $S n / H Cl$

Diazotisation, $C u CN / K CN$ , $H_{2} O / H^{+}$

Diazotisation, $N a CN$ , $N a O H$

Toluene on nitrification gives $p$ -nitro toluene, which on reduction with $S n / H Cl$ gives $p -$ toluidine diazonium chloride salt, this on reaction with $C u CN / K CN$ gives 4- methyl benzonitrile, which on hydrolysis gives $p$ -toluric acid.
