Most toxic reactions of a serious nature are related to excessive blood levels arising from inadvertent intravascular injection. Hypersensitivity reactions (options b & c) are rare, but excessive blood levels will induce toxic reactions like CNS stimulation in most everyone. This is a case where option (e) is the "best" answer, because it is more likely than the other alternatives, which might be true, but are not as likely (e.g, “most probable”) to happen.
