(D) According to Fajan's rule,covalent character increases as the size of the cation decreases and its charge density increases. Among the alkaline earth metal ions ($Mg^{2+}$,$Ca^{2+}$,$Sr^{2+}$,$Ba^{2+}$),the $Mg^{2+}$ ion has the smallest size. Therefore,$MgCl_2$ exhibits the most significant covalent character among the given halides.
