1-Methylcyclohexene is treated with $BH X_{3} \cdot THF$ and then $H X_{2} O X_{2} / NaOH$ . The major product is

A3-methylcyclohexan-1-ol
B1-methylcyclohexan-1-ol
Ctrans-2-methylcyclohexan-1-ol
Dcis-2-methylcyclohexan-1-ol

Answer: C

Boron adds to the less substituted ring carbon, and H adds to the methyl-bearing carbon on the same face (syn). Oxidation replaces B by OH with retention. The new H and OH are cis, so OH and

CH X_{3}

are trans.
