Among the given compounds I-III, the correct order of bond dissociation energy of C-H bond marked with * is :

Bond dissociation energy depends on the stability of the free radical formed. Compound III is cyclopropene (allylic/strained \( sp^3 \) carbon forming antiaromatic/strained radical), II is \( \text{sp} \) hybridized \( \text{C}-\text{H} \) bond in phenylacetylene derivative (very high BDE), I is benzylic \( ext{C}- ext{H} \). Stability order gives bond dissociation energy order: \( \text{II} > \text{I} > \text{III} \).
