The correct answer is option B.
The liquid or gas that carries the sample across the solid support is called mobile phase.
In chromatography, there are two phases: mobile phase and solid phase.
The mobile phase can be either in gas form or liquid form.
While performing the chromatography technique, mobile phase moves over the stationary phase and its components adsorb to the stationary phase and set apart from each other at different rates.
In general, mobile phase refers to the solvent phase that slides over the stationary phase through the chromatography paper.
on the other hand, stationary phase is motionless.

In complex compounds coordination number is the number of atoms or polyatomic ions surrounding the central metal. In given statement the coordination number given is 6, means there are 6 ligands surrounding the metal atom, and the ligands given are only NH₃, so 6 NH₃ molecules are surrounding the Cobalt atom. Hence,
[Co (NH₃)₆]
As, NH₃ is neutral so the charge on sphere will be the charge on Co, as charge given in statement id +3 so,
[Co (NH₃)₆]³⁺
Name of this complex is as follow,
Hexaamminecobalt (III) Ion
Answer:
Dipole, less electronegativity, higher electronegativity
