On his mother side, Babur belonged to which of the following?

Ghenghis Khan

The correct answer is Option 4- Ghenghis Khan

On his mother's side, Babur belonged to Genghis Khan.

Babur's mother, Qutlugh Nigar Khanum, was a descendant of Genghis Khan through his son Chagatai Khan. The Chagatai Khanate was one of the four khanates that emerged from the Mongol Empire after Genghis Khan's death.

Babur was proud of his Mongol heritage on his mother's side. He often referred to himself as a "Chagatai prince" and claimed to be a descendant of Alexander the Great, who he believed was also a Mongol.

The other options you mentioned are incorrect:

• Timur was not related to Babur on his mother's side.
• Turkish is a language, not a people group. Babur's mother was not Turkish.
• Afghans are a people group who live in Afghanistan and Pakistan. Babur's mother was not an Afghan.
