Give the reactivity in the decreasing order of the following nucleophiles towards nucleophilic addition reaction with compound A $\left({\mathrm{F}}_3\mathrm{C}-\equiv -{\mathrm{CF}}_3\right)$.

$$\begin{gathered} \text{ (I) }{\mathrm{CH}}_3{\mathrm{O}}^{-} \left(\mathrm{II}\right) {\mathrm{C}}_2{\mathrm{H}}_5{\mathrm{O}}^{-} \\ \text{ (III) }{\mathrm{CH}}_3{\mathrm{COO}}^{\ominus }\text{ (IV) }{\mathrm{CH}}_3{\mathrm{SO}}_3^{\ominus } \end{gathered}$$

In the same nucleophilic centre, nucleophlilicity is parallel to basic character. Stronger the acid, weaker is the conjugated base.
Acidic character order: ${\mathrm{CH}}_3{\mathrm{SO}}_3\mathrm{H}>{\mathrm{CH}}_3\mathrm{COOH}>{\mathrm{CH}}_3\mathrm{OH}>{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}$
Basic and nucleophilicity order:
$$\begin{gathered} {\mathrm{CH}}_{3}S{O}_3^{-}<{\mathrm{CH}}_3{\mathrm{COO}}^{\ominus }<{\mathrm{CH}}_3{\mathrm{O}}^{\ominus }<{\mathrm{C}}_2{\mathrm{H}}_5{\mathrm{O}}^{-} \\ \left(\mathrm{IV}\right) \left(\mathrm{III}\right) \left(\mathrm{I}\right) \left(\mathrm{II}\right) \end{gathered}$$
