$\mathrm{A}+\mathrm{B}\to {\mathrm{CH}}_3-\mathrm{OC}{\left({\mathrm{CH}}_3\right)}_3\stackrel{\mathrm{HI}}{⟶}\mathrm{X}+\mathrm{Y}.$
Correct statement among the following is

$\mathrm{A}\text{ and }\mathrm{B}\text{ are }{\mathrm{CH}}_3\mathrm{ONa}\text{ and }{\left({\mathrm{CH}}_3\right)}_3\mathrm{CBr}$

$\mathrm{X}\text{ and }\mathrm{Y}\text{ are }{\mathrm{CH}}_3\mathrm{I}\text{ and }{\left({\mathrm{CH}}_3\right)}_3\mathrm{COH}$

$\mathrm{X}\text{ and }\mathrm{Y}\text{ are }{\mathrm{CH}}_3\mathrm{OH}\text{ and }{\left({\mathrm{CH}}_3\right)}_3\mathrm{CI}$

$\mathrm{A}\text{ and }\mathrm{B}\text{ are }{\mathrm{CH}}_3\mathrm{OH}\text{ and }{\left({\mathrm{CH}}_3\right)}_3\mathrm{COH}$
