[Cr (NH₃) ₆]Cl₃

Explanation:

The transition metal compound most likely to form a yellow solution is the complex of [Cr (NH₃) ₆]Cl₃,

Transition metals belongs to the d-block on the periodic table. They are made up of atoms whose d-subshell are partially or fully filled.

Most these elements have variable oxidation states and exhibits colored properties. They display a wide range of colors.

[Cr (NH₃) ₆]Cl₃ is a complex that absorbs other wavelength of light but reflects yellow light making it visibly yellow.

The colors originates from the transition of electrons through electronic orbitals and thereby giving off corresponding light that we visibly observe.
