1-Methylcyclohexene is treated with $Br X_{2}$ in water and the resulting bromohydrin is then treated with aqueous $NaOH$ . The final organic product is

A1-methylcyclohexene
B2-methylcyclohexan-1-one
C1-methyl-7-oxabicyclo[4.1.0]heptane (1-methylcyclohexene oxide)
D1-methylcyclohexane-1,2-diol

Answer: C

The first step gives trans-2-bromo-1-methylcyclohexan-1-ol, with Br on C2 and OH on the tertiary C1. Base forms the alkoxide, which displaces the adjacent anti bromide by intramolecular SN2. The product is the epoxide.
