Which among the following is a Muslim majority province of British India that had large areas where the non-Muslims were in majority?

Punjab

The correct answer is Option (3) → Punjab

• Punjab was a Muslim-majority province in British India.
• However, it had significant regions (especially in eastern Punjab) where non-Muslims (Hindus and Sikhs) were in majority. 

Hyderabad and Junagadh were princely states, not province.
