Correct answer
Cv<iii<ii<iv<i

Step-by-step explanation

Basicity is inversely proportional to electronegativity.

Higher the electron affinity or core charge of an atom, the less likely it is to donate its electrons to a proton.
Greater the delocalization of electrons that could potentially donate to a proton, the less able they are to donate.
Greater the electron-withdrawing effects in another part of a molecule, the less likely the electrons on a particular atom are to donate.
