Step 1: Recall the Background:
Write the Mughal rulers in order from the first: Babur, Humayun, Akbar, Jahangir, Shah Jahan. The one right after Babur is the answer.
Step 2: Test every option one by one:
1. Shah Jahan: fifth in order, so he is too late.
2. Jahangir: fourth in order, so he is too late.
3. Akbar: third in order, so he came after Humayun.
4. Humayun: second in order and the direct heir of Babur, so this is the match.
Step 3: Confirm the result:
Only option 4 (Humayun) passes the test above, and the other three fail for the reasons given. This also agrees with the standard fact: Babur founded the Mughal Empire in 1526 and died in 1530. His son Humayun became the next emperor. The order of rule is Babur, Humayun, Akbar, Jahangir, Shah Jahan.
Final Answer:
Option 4, Humayun.
\[\boxed{4}\]
Quick Recheck:
Read the question once more: Which of the following emperor succeeded Babur ? The answer must match this exact wording, and option 4 (Humayun) is the only one that does. The other options are different artists, places, rulers or styles, so they cannot be chosen.
