Statement–I : the following compound is optically inactive      Statement–II : It has two chiral carbons

Statement-I: The optical activity of a compound is determined by its ability to rotate plane-polarized light. A compound is optically inactive if it does not rotate plane-polarized light. This can occur if the compound is achiral (not chiral), or if it is a racemic mixture (a 1:1 mixture of two enantiomers).

Statement-II: A chiral carbon is a carbon atom that is attached to four different types of atoms or groups of atoms. Having two chiral carbons does not necessarily mean that the compound is optically active. It could be optically inactive if it is a meso compound. Meso compounds have multiple chiral centers but are optically inactive due to a plane of symmetry, which results in a cancelation of the rotation of plane-polarized light.

So, the compound in Statement-I could be optically inactive even though it has two chiral carbons (Statement-II) if it is a meso compound.
