Correct Answer - C
Lanthanides show +4 O.S. in `f ^(0), and f^(7)` configuration, whereas it is possible to attend stable electronic configuration. i.e., `(+3` to `+4`) But they does not show +4 O.S. in `4f^(14)` configuration because, by lose of three electrons they already acquire `4f^(14)` configuration i.e. `(+3` to `+4)` O.S. Hence `+4` O.S. is not possible in `4f^(14)` configuration.
