Cyclohexene reacts with $Br X_{2}$ in water. The major product is

Acyclohexane-1,2-diol
Bbromocyclohexane
Ctrans-2-bromocyclohexan-1-ol
Dcis-2-bromocyclohexan-1-ol

Answer: C

Water attacks the cyclic bromonium ion from the side opposite to bromine (anti addition). Br and OH end up trans, giving trans-2-bromocyclohexan-1-ol.
