Hint: We know that the isomers which can rotate the plane of polarized light are known as the optically active complexes. The essential condition for the complex to exhibit the optical activity is that the isomer should not possess the plane of symmetry in the structure.

Complete answer:
If the plane divides the complex into the equal half then the complex is optically inactive. However, if not then the complex is said to be optically active. The bidentate ligand donates its two electrons and forms a bond with the metal. There is a certain substance that can rotate the plane polarized light. These are called the optically active substances.

The isomers which rotate the plane of polarized light equally but in opposite directions are called the optically active isomers. The essential condition for a substance to show optical activity is that the substance should not have a plane of symmetry in its structure. The optical isomers have identical physical and chemical properties. They differ only in the direction in which they rotate the plane of polarized light.
Therefore, the correct answer is option A.

Note:
Remember that the similarities between a racemic mixture and meso compound are that they both are organic compounds and are optically inactive. The main difference between them is that a racemic mixture contains non-identical isomers while a meso compound contains an identical isomer.
