List-II
A. $\mathrm{CH_3COOH}$ in pyridine
(i) strong acid
B. $\mathrm{CH_3COOH}$ in $\mathrm{H_2SO}$
(ii) weak acid
C.$\mathrm{HClO_4}$ in $\mathrm{H_2SO_4}$
(iii) strong base
D. $\mathrm{SbF_5}$ in HF
(iv) weak base
(a)(A-i), (B-ii), (C-iii), (D-iv)
(b)(A-ii), (B-i), (C-in), (D-iv)
(c)(A-iii), (B-iv), (C-ii), (D-i)
