Explanation:

Pakistani Senate panel sought a report from the interior ministry on the action taken against terrorists involved in the killing of Hazaras, the minority Shia community. This comes a day after a suicide blast killed 21 people in restive Balochistan province.

The Hazaras are an ethnic group who are mainly concentrated in the mountainous central region of Afghanistan known as Hazarajat. There is also a Hazara population in Baluchistan, Pakistan. Most Pakistani Hazaras today live in the city of Quetta, in Balochistan. Hence option(c) is correct.

The Hazaras believe themselves to be descendants of the Turko-Mongol tribes of Asia. However, there is little precise knowledge about their ethnic origins. Most Hazaras today speak Dari, a form of Persian, also called Khorasani Persian. In addition to Persian, some Hazaras also speak Pashtu, Baluchi, and Turkic.
