The correct set of reagents required for the following transformation is 
(a)(i) $\mathrm{CrO}_{3}$; (ii) acrylonitrile; (iii) $\mathrm{H}_{3} \mathrm{O}^{+}$
(b)(i) $\mathrm{O}_{2}$; (ii) methyl acrylate
(c)(i) $\mathrm{CrO}_{3}$; (ii) NaOMe/MeOH, methyl acrylate; (iii) $\mathrm{H}_{3} \mathrm{O}^{+}$
(d)(i) $\mathrm{H}_{2} \mathrm{O}$; (ii) methyl acrylate
Answer
Answer: C ✓ checked by 4AB · confidence high
Explanation
CrO₃ oxidises cyclohexanol to cyclohexanone. NaOMe/MeOH forms the enolate, which undergoes Michael addition to methyl acrylate, giving methyl 3-(2-oxocyclohexyl)propanoate (c).
