- **Paramagnetic complex formation**

Nickel (Z = 28) combines with a uninegative monodentate ligand X − to form the paramagnetic complex [NiX4]2−.

- **Number of unpaired electrons**

The presence of unpaired electrons in a complex is responsible for its paramagnetic nature. In this case, the complex [NiX4]2− has two unpaired electrons in the nickel atom.

- **Geometry of the complex ion**

The coordination number of nickel in the complex is 4, indicating a tetrahedral geometry. This geometry is achieved when a metal ion is surrounded by four ligands in a way that they are positioned at the four corners of a tetrahedron around the central metal ion.

Therefore, the correct answer is option 'D', which states that there are two unpaired electrons in the nickel atom and the geometry of the complex ion is tetrahedral.
