Explanation:

Let’s break down each option:

- Option 1: Humayun

Shivaji wasn’t even born when Humayun ruled. Their timelines don’t match at all.

- Option 2: Shahjahan

Shivaji was born during Shahjahan’s reign, but never really clashed with him directly. Not the key opponent.

- Option 3: Akbar

Akbar died before Shivaji was born, so they never could have faced off.

- Option 4: Aurangzeb

This is the one. Shivaji and Aurangzeb had serious conflicts, both militarily and politically. These two are famous for their struggle, with Shivaji resisting Aurangzeb’s empire at every turn.

So the answer: Shivaji fought against Aurangzeb. Option 4, and you nailed it.
