Given below are two statements: one is labelled as Assertion \((A)\) and the other is labelled as Reason \((R).\) Assertion \((A) :\) Treatment of bromine water with propene yields \(1-\)bromopropan\(-2-\)ol. Reason \((R):\) Attack of water on bromonium ion follows Markovnikov rule and results in \(1-\)bromopropan\(-2-\)ol. In the light of the above statements, choose the most appropriate answer from the options given below:
