Increasing order (least basic first) of basic strength is shown by the set

The decreasing order of acid strength by the following sequence of reaction is

Correct arrangement of the following acids in correct ${\mathrm{K}}_{\mathrm{a}}$ order is

(I) ${\mathrm{H}}_3{\mathrm{N}}^{\oplus }-{\mathrm{CH}}_2-\mathrm{COOH}$

(II) $\mathrm{NC}-{\mathrm{CH}}_2-\mathrm{COOH}$

(II) ${\mathrm{H}}_3\mathrm{C}-{\mathrm{CH}}_2-\mathrm{COOH}$

(IV) $\stackrel{⊝}{\mathrm{O}}\mathrm{OC}-{\mathrm{CH}}_2-\mathrm{COOH}$
