Answer:

FeBr3 is the Lewis acid, and FeBr4-1 is the Lewis base.

Explanation:

A Lewis acid is any specie that has empty orbitals into which it can receive a lone pair of electrons.

A Lewis base is any specie that donates a lone pair of electrons to another to form a dative covalent bond.

If we look at the species listed in the options, FeBr3 is lone pair acceptor hence it is a Lewis acid while FeBr4- is a lone pair donor hence it is Lewis base.
