Match the entries of column I with appropriate entries of column II and choose the correct option out of four options \( (a),(b),(c),(d) \) given at the end of each question.
\( \begin{array}{llll}\text { (A) } & \text { Column I } & \text { Column II } \\ \text { sodium benzoate when heated with } & (p) & \text { Electrophilic substitution } \\ \text { soda-lime gives benzene. } & & \\ \text { Treatment of ethanol with conc. } \mathrm{H}_{2} \mathrm{SO}_{4} & (q) & \text { Nucleophilic substitution } \\ \text { at } 433-443 \mathrm{~K} \text { gives ethene. } & \\ \text { (C) Phenylmagnesium bromide on treatment } & \text { (r) } & \text { Dehydration } \\ \text { with } \mathrm{D}_{2} \mathrm{O} \text { gives deuterated benzene. } & & \\ \text { (D) Benzene on nitration with a mixture of conc. (s) } & \text { Decarboxylation } \\ \mathrm{HNO}_{3}+\text { conc. } \mathrm{H}_{2} \mathrm{SO}_{4} \text { gives nitrobenzene. } & \end{array} \)
(A) A-s; B-r; C-q; D-p
(B) A-r ; B-s; C- \( p ; \) D- \( q \)
(C) A- \( p \); B- \( q \); C- \( r \); D- \( -s \)
(D) A- \( -q ; \) B- \( p ; \) C-s ; D-r
