(A) The given molecule is a derivative of a central cyclobutane ring substituted with two oxetane rings and two bromine atoms. To determine optical activity,we must check for the presence of a plane of symmetry $(POS)$ or a center of inversion $(COS)$. If we examine the structure,the two bromine atoms can be oriented in different spatial arrangements relative to the central cyclobutane ring (cis or trans). However,in both the $cis$ and $trans$ configurations,the molecule possesses a plane of symmetry passing through the two carbon atoms bearing the bromine atoms or through the center of the cyclobutane ring. Since the molecule has a plane of symmetry in all its possible stereoisomeric forms,it is achiral. Therefore,the number of optically active isomers is $0$.
