નીચેની પ્રક્રિયા શ્રેણીમાં $X$ અને $Y$ શું છે?
$Propene$ $\xrightarrow{HBr} A$ $\xrightarrow[Dry \ ether]{Mg} B$ $\xrightarrow[2. H_3O^{+}]{1. X} Y$

• A
  $X = \text{Pentan-2-one}$,$Y = \text{2,3-dimethylhexan-3-ol}$
• B
  $X = \text{Butan-2-one}$,$Y = \text{2,3-dimethylpentan-3-ol}$
• C
  $X = \text{Pentan-3-one}$,$Y = \text{3-ethyl-2-methylpentan-3-ol}$
• D
  $X = \text{2-methylpentan-3-one}$,$Y = \text{3,4-dimethylhexan-3-ol}$
