Describe the First Step of a Specific-Base-Catalyzed Dehydration of a Hydrate

Describe the first step of a specific-base-catalyzed dehydration of a hydrate.

A) Base abstracts a proton,electron pair from O-H bond goes to oxygen.
B) Negative charge from oxygen forms double bond,hydroxide departs as leaving group.
C) Base abstracts a proton,electron pair from O-H bond forms a double bond,hydroxide departs as leaving group.
D) Hydroxide departs as leaving group,then negative charge from oxygen forms a double bond.
E) Electron pair from O-H bond forms a double bond,base abstracts a proton.
