Solution

The correct option is A Lanthanides are separated from one another by ion exchange methods
The ionic radii of trivalent lanthanides steadily increases with increase in atomic number. All Lanthanides are highly dense metals with a general oxidation state of +3.
Hence, Option "A" is the correct answer.
