Concept:Identify the well-known figure who was actually killed during the Battle of Badr.
Explanation:The Battle of Badr was the first major clash between the Muslims of Madinah and the Quraysh of Makkah.
The Muslims won this battle despite being smaller in number.
Abu Jahl, whose real name was Amr ibn Hisham, was a leading enemy of Islam.

Abu Sufyan was present at Badr but escaped.
Khalid ibn Walid also survived and later accepted Islam.
Therefore, among the given options, the one killed at the Battle of Badr was Abu Jahl.
