Answer:

Correct Answer: B

Solution:

$ \underset{\text{2Methyl-2-hydroxy propane }}{\mathop{CH_3-\overset{\overset{C{H_3}}{\mathop{|}}}{\mathop{\underset{\underset{OH}{\mathop{|}}}{\mathop{C-CH_3}}}}}}\underset{Dehydration}{\mathop{\xrightarrow{H_2SO_4}}}\underset{\begin{smallmatrix} \\ Isobutene \end{smallmatrix}}{\mathop{CH_3-\overset{\overset{CH_3}{\mathop{|}}}{\mathop{C=}}CH_2}}+H_2O $
