The correct answer is C. Sansar Chand.
The Kangra school of painting was a style of Indian painting that flourished in the Kangra Valley in the 18th and 19th centuries. It is characterized by its use of bright colors, delicate brushwork, and detailed depictions of nature. The school was patronized by the Kangra rulers, and its most famous artists include Nainsukh, Manaku, and Basohli.
Ghumand Chand was the ruler of Kangra from 1664 to 1695. He was a patron of the arts, and he commissioned a number of paintings from the Kangra school. However, the school did not reach its full flowering until the reign of his grandson, Sansar Chand.
Sansar Chand was the ruler of Kangra from 1700 to 1770. He was a great patron of the arts, and he commissioned a large number of paintings from the Kangra school. Under his patronage, the school reached its peak of development. The paintings produced during this period are some of the finest examples of Indian miniature painting.
Jai Singh Kanheya was the ruler of Kangra from 1770 to 1783. He was not a patron of the arts, and the Kangra school declined during his reign.
Rajit Singh was the ruler of Kangra from 1783 to 1803. He was also not a patron of the arts, and the Kangra school continued to decline during his reign.
In the early 19th century, the Kangra school of painting declined due to a number of factors, including the decline of the Kangra kingdom, the rise of the Sikh Empire, and the introduction of Western art. However, the school has experienced a revival in recent years, and its paintings are now highly prized by collectors.
