Question

Given below are two statements : Statement (I) : In the Lanthanoids, the formation of $\mathrm{Ce}^{+4}$ is favoured by its noble gas configuration.\ Statement (II) : $\mathrm{Ce}^{+4}$ is a strong oxidant reverting to the common +3 state. In the light of the above statements, choose the most appropriate answer from the options given below :\
