According to the Lewis acid-base concept:

Aspecies in which the central atom has completed octet can not act as an acid
Bnegative charged ions are acids
Cmolecule in which a central atom has vacant d-orbitals available acts as an acid
Correct Answer
Dall positively charged ions are bases

Solution

According to Lewis acid-base concept. the atom which accepts the pair of electron is called Lewis acid and the atom which donate a pair of electron is called a Lewis base. If the atom has a vacant d-orbital, then it can easily accept a pair of electron and thus, it can act as a Lewis acid.
