Solution
The correct option is CI and III If either of the ends of allene is attached to two identical substituents, then it is achiral. It is because it will have plane of symmetry.
If neither of the ends are attached to two identical substituents, then it is chiral.
In case of II, each of the ends have identical substituents. So it doesn't show optical activity. I and III are optically active.
