"In an investigative organic chemistry experiment, a compound 'Q' with the molecular formula C6H12O2 is analyzed. 'Q' does not react with Tollens' reagent, indicating it is not an aldehyde. It also does not form any precipitate with 2,4-Dinitrophenylhydrazine (2,4-DNP), suggesting the absence of a free carbonyl group. When 'Q' is treated with hydroxylamine (NH2OH), no reaction occurs, which implies that 'Q' does not contain an ester group. Additionally, 'Q' does not react with sodium metal, indicating the absence of acidic hydrogen. In a distinctive reaction, when 'Q' is treated with LiAlH4 (lithium aluminium hydride), it yields a compound 'R' with the formula C6H14O2. Based on these observations, what is the most likely structure of compound 'Q'?" A. Isopropyl butyrate B. Diethyl ether C. Diisopropyl ether D. 1,4-Dioxane
