Solution

The correct option is D
van der Waals radius is always larger than covalent radii

Covalent radius is half of the distance between two similar atoms joined by single covalent bond in same molecule.

van der Waals radius is one half of the distance between two similar adjacent atoms belonging to two nearest neighbouring molecules of the same substance in the solid state.

It is always larger than covalent radii.
