Which of the following statement is wrong?

Among the following elements :
`K, Mn, Ca, Cs, Fe, Cu, Pb, Os, Y`
The number of transition element is `4`.

All the lanthanides and actionides belong to `III B` or the `3rd` group in the periodic table.

The inner transition elements belong to the `f`-block of the periodic table and are shown separately at the bottom of the periodic table.

The `d`-block elements have variable valency.
