Answer: The pair of ions that is most likely to form an ionic bond is
Mg^(2+)\text{ and }Br^-

Step-by-step explanation:

Ionic compound is defined as the compound which is formed by complete transfer of electrons from one atom to another atom.

The atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom. This bond is usually formed between a metal (carrying positive charge) and a non-metal (carrying negative charge)

Ionic compound is formed by the attraction of oppositely charged ions.

For the given options:

Magnesium ion
(Mg^(2+)) and bromine ion
(Br^-) will attract each other because they are oppositely charged and will lead to form ionic compound.

The ionic compound formed is magnesium bromide
(MgBr_2)

Hence, the pair of ions that is most likely to form an ionic bond is
Mg^(2+)\text{ and }Br^-
