What is incorrect about Sansar Chand's later life and the matured Kangra kalam paintings?

Sansar Chand shifted to Alampur

The correct answer is Option 3- Sansar Chand shifted to Alampur.

Raja Sansar Chand established supremacy of Kangra over all surrounding hill states. Tira Sujanpur emerged as the most prolific centre of painting under his patronage. An earlier phase of Kangra kalam paintings is witnessed in Alampur and the most matured paintings were painted at Nadaun, where Sansar Chand shifted later in his life. All these centres were on the banks of river Beas. Alampur along with river Beas can be recognised in some paintings. Less number of paintings was done in Kangra as it remained under the Mughals till 1786, and later, the Sikhs.
