  2. In cis-isomers, the two identical ligands occupy the positions diagonal to each other.

D Correct answer
Explanation

Geometrical isomerism is a subtype of stereoisomerism where isomers differ in spatial arrangement but not in bonding connectivity. Geometrical isomers have different physical properties. Cis-isomers have identical ligands adjacent; trans-isomers have them opposite.
