(a)
Interpretation: The geometrical isomers of the given compounds are to be determined.
Concept introduction: The geometrical isomer or cis-trans isomers are the isomers with different spatial arrangements of the groups attached to the central atom.
In cis isomer, two of the liked groups are placed adjacent to each other. While in trans isomers, the two liked groups are placed opposite to each other.
To determine: The geometrical isomers of
