Solution
The correct option is A Dextrorotatory
We usually call compounds which can rotate plane polarised light in the clockwise direction as Dextrorotatory.
Similarly, the compounds which can rotate plane polarised light in the anticlockwise direction are called Laevorotatory.
If you are confused whether to use R/S or D/L here, let me clear that for you. R/S nomenclature is used to denote the way in which the molecules in the compounds are oriented in space which helps us differentiate between stereoisomers in a simple and effective way. It has nothing to do with the way it can rotate light.
An R molecule may be either D/L. There is no link between R/S and D/L.
Please don't forget this!
