The correct basicity order of the following lanthanide ions is
(A) \(\mathrm{La}^{3+}>\mathrm{Lu}^{3+}>\mathrm{Ce}^{3+}>\mathrm{Eu}^{3+}\)
(B) \(\mathrm{Ce}^{3+}>\mathrm{Lu}^{3+}>\mathrm{La}^{3+}>\mathrm{Eu}^{3+}\)
(C) \(\mathrm{Lu}^{3+}>\mathrm{Ce}^{3+}>\mathrm{Eu}^{3+}>\mathrm{La}^{3+}\)
(D) \(\mathrm{La}^{3+}>\mathrm{Ce}^{3+}>\mathrm{Eu}^{3+}>\mathrm{Lu}^{3+}\)
