Question

$CH_{3}\overset{\underset{||}{O}}{C}CH_{2}CH_{2}\overset{\underset{||}{O}}{C}OCH_{2}CH_{3}\underset{(ii) H_{3}O^{+}}{\overset{(i) CH_{3}MgBr (one mole)}{\longrightarrow}}A$
A is formed in this reaction is

• A. $CH_3\underset{\overset{|}{C}H_3}{\overset{\underset{|}{O}H}{C}}CH_2CH_2\overset{\underset{||}{O}}{C}OCH_2CH_3$
• B. $CH_3 \overset{\underset{||}{O}}{C}CH_2CH_2\overset{\underset{||}{O}}{C}CH_3$
• C.
• D. $CH_3 \underset{\overset{|}{O}H}{\overset{\underset{|}{C}H_3}{C}}CH_2 \,\,CH_2\underset{\overset{|}{O}H}{\overset{\underset{|}{C}H_3}{C}}CH_3$
