Optical rotations of some compounds along with their structures are given below which of them have D configuration.
(i) I, II, III
(ii) II, III
(iii) I, II
(iv) III
The answer is the option (i). All of the given compounds have D-configuration due the presence of -OH group of asymmetric carbon on the right side. So, Option (i) I, II, III is the answer.
