Cyclohexene is treated with $Br X_{2}$ / $H X_{2} O$ and the product is then treated with aqueous $NaOH$ (cold). The final major product is

Acyclohexene oxide
Bcyclohexane-1,2-diol
Ccyclohexanone
Dcyclohexa-1,3-diene

Answer: A

Bromine water gives trans-2-bromocyclohexan-1-ol (a bromohydrin). Base deprotonates OH, and the alkoxide displaces bromide intramolecularly (anti arrangement) to close the epoxide ring.
