Question

$CH_3\overset{\underset{||}{O}}{C}CH_2CH_2\overset{\underset{||}{O}}{C}OCH_2CH_3 \ce{->[(i) CH_3MgBr \text{(one mole)}][(ii) H_3O^+]} A$
$A$ 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. $CH_3 \underset{\overset{|}{O}H}{\overset{\underset{|}{C}H_3}{C}}CH_2 \,\,CH_2\underset{\overset{|}{O}H}{\overset{\underset{|}{C}H_3}{C}}CH_3$
