Correct Answer: Karakoram Ranges

Solution : The correct option is Karakoram Ranges.

The Baltoro Glacier is located in Pakistan's Gilgit-Baltistan province, in the Karakoram Range of the Himalayas. It is one of the world's longest and biggest glaciers outside of the polar regions, and it is noted for its breathtaking scenery and link to some of the world's highest peaks, including K2, the world's second-highest mountain. The Shigar River rises from the Baltoro Glacier, an important river in Pakistan's Gilgit-Baltistan area, and runs through the Shigar Valley before entering the Indus River.
