The correct answer is: c) Islam.
The Shah Miri dynasty was a Muslim dynasty that ruled over Kashmir from the 14th to the 16th centuries. They were the first Muslim dynasty to rule Kashmir, and they brought Islam to prominence in the region.
Hinduism was the dominant religion in Kashmir before the arrival of the Shah Miri dynasty. However, the Shah Miri rulers promoted Islam and built many mosques and madrasas in the region. As a result, Islam became the dominant religion in Kashmir by the end of the 16th century.
Buddhism was also a major religion in Kashmir before the arrival of the Shah Miri dynasty. However, it declined in popularity after the arrival of Islam. Today, there are only a few thousand Buddhists living in Kashmir.
Sikhism is a relatively new religion that was founded in the 16th century. It is not a major religion in Kashmir, and there are only a few thousand Sikhs living in the region.
