\text{Ti}^{2+}

(atomic number 22) and

\text{V}^{3+}

(atomic number 23) are both present in aqueous solution. Which statement correctly compares their magnetic properties? (a) Both

\text{Ti}^{2+}

and

\text{V}^{3+}

have no unpaired electrons and are diamagnetic. (b) Both

\text{Ti}^{2+}

and

\text{V}^{3+}

have three unpaired electrons and are equally paramagnetic. (c) Both

\text{Ti}^{2+}

and

\text{V}^{3+}

have two unpaired electrons and are equally paramagnetic. (d)

\text{V}^{3+}

has one more unpaired electron than

\text{Ti}^{2+}

and is more paramagnetic.
