What are some of the offshoots of the Basohli style of painting?

Chamba, Kullu, Nurpur

The correct answer is Option 2-  Chamba, Kullu, Nurpur

The Kangra School came to fore in the 1780s while the offshoots of the Basohli style emerged and continued in centres such as Chamba, Kullu, Nurpur, Mankot, Jasrota, Mandi, Bilaspur, Jammu and others with some of their specific characteristics. In Kashmir (1846–1885), the Kangra style initiated a local school of Hindu book illumination. The Sikhs employed other Kangra painters eventually.
