Solution

The correct option is D 14 elements in the sixth period (atomic no. = 58 to 71) that are filling 4 f-sublevel
The elements in which the additional electrons enters (n-2)f orbitals are called innertransition elements. 4f-block elements are also called lanthanides or rare earths so lanthanides are 14 elements in the sixth period (atomic no. = 58 to 71) that are filling 4 f-sublevel.
