first break the bonds jo free radical banega uski stability check kar if the free radical is stable then the bond is weak so the least stable free radical will have the strongest CH bond

wtf Ha sabse unstable kahan hai Hb hona chahiye sabse unstable

Hb remove karo it will be the most unstable hence it’s bond energy should be stronger

Haan to wo theek hai Ha and Hd mein to Hd more stable hai na to bond energy least honi chahiye

Hb is highest bond energy since it's hard to break partial sp2 character bond then Hc since breaking Hc forms primary carbocation then Hd since breaking Hd forms tertiary carbocation then Ha since the carbocation formed by breaking Ha is resonance stabilized because of the double bond Hb > Hc > Hd > Ha, matches with option C
