Solution:

The reactivity of carbonyl compound towards nucleophilic addition of Grignard's reagent depends on extent of steric hindrance at $\alpha$-carbon. Greater the steric hindrance smaller the reactivity. Hence, reactivity order is
$\underset{II}{CH _{3} CHO} > \underset {I}{CH _{3}- CO - CH _{3}} > \underset{III}{Ph - CO - Ph}$
