Catalytic dehydration of tertiary alcohol

(D) The correct answer is $D$. When vapours of a tertiary alcohol are passed over heated copper $(Cu)$ at $573 \, K$,it undergoes dehydration to form an alkene because tertiary alcohols lack $\alpha$-hydrogen atoms required for dehydrogenation.$CH_3-C(OH)(CH_3)-CH_3 \xrightarrow{Cu, 573 \, K} CH_3-C(CH_3)=CH_2 + H_2O$
