A similarity between optical and geometrical isomerism is that

Options

A. they have no similarity
B. both are included in stereoisomerism
C. if in a compound, one is present than so is the other
D. each forms equal number of isomers for a given compound

Answer

B

Explanation

Both optical and geometrical isomers are stereoisomers. Optical isomers correspond to enantiomers i.e. steroisomers that are nonsuperposable mirror images with geometrical isomers are exaples of diastereomers i.e. steroisomers that are not mirror images of each other.
