The correct order of boiling points of below compounds is
1 (I) $>$ (II) $>$ (III)
2 (II) $>$ (I) $>$ (III)
3 (III) $>$ (II) $>$ (I)
4 (II) $>$ (III) $>$ (I)
Explanation:
The boiling point increase when the ERG increase. Hence, boiling point, II > III > I

3 (B) $>$ (D) $>$ (C) $>$ (A)
4 (B) $>$ (C) $>$ (D) $>$ (A)
Explanation:
(C) : Stability depends upon the order of $+\mathrm{R}$ effect. $+\mathrm{R}$ effect is shown by electron donating group. Hence, the stability order $=\mathrm{B}>\mathrm{D}>\mathrm{C}>\mathrm{A}$
