Geometric (cis-trans) isomers are compounds which have the same chemical formula but differ in the spatial arrangement of the groups that are attached to a double bond or to a ring. Two necessary conditions for a compound to possess geometrical isomerism: (i) It must contain a carbon-carbon double bond in the molecule.
(ii) Two unlike atoms or groups must be linked to each doubly bonded carbon atoms. Geometrical isomerism among alkenes does not occur when the doubly bonded carbon carry identical atoms or groups. For example, AAC = CAB does not exhibit geometrical isomerism. All given options are correct and possess double bond, two unlike atoms are attached to each double bonded carbon atom.
