ANSWER

The given image is Self-Explanatory.

We know that following are the cases when a compound is Optically Inactive:

1. When it does not have a chiral Carbon Atom eg.: Methyl bromide

2. When it has a Plane or Axis of Symmetry eg.: Tartaric Acid (these compounds are called as Meso Compounds)

3. When it forms a Racemic Mixture eg.: Equimolar mixture of d-Lactic Acid and l-Lactic Acid.

The given compound in the question possesses an Axis of Symmetry (shown in the attached image). Hence, it is Optically Inactive.
