A center of symmetry (inversion center) is a point where every part of the molecule has an identical part directly opposite it. For a compound to possess a center of symmetry, its structure must be such that for every atom at coordinates (x, y, z), there is an identical atom at (-x, -y, -z).
Among the given options, the compound with a planar, symmetric structure and identical substituents arranged opposite each other will have a center of symmetry. The first image depicts a symmetric, trans-like configuration, which is a classic example of a molecule with a center of symmetry.
Final Answer: The first compound (top-left image) has a center of symmetry.
