Explanation:
Ionic bond is a type of bond in which one or more atoms are transferred to another atom which results to two ions with opposite charge. They attract each other.
The atom of another element is removed and then gained by another element which produces a noble gas electron configuration.
Covalent bond is a type of bond in which a pair or more electrons are being shared by the atoms of two elements.
Because of this, the molecules become stable by sharing the electrons thus creating a noble gas configuration for each of the atom.
A substitution is a mutation that exchanges one base for another. This can include a change in a single chemical letter. ex. changing a to g or in your case g to a. I believe the correct answer should be B.
