Detailed Explanation:

The passage mentions art forms from four states: Bengal's Pattachitra paintings, Assam's bamboo crafts, Tamil Nadu's Thanjavur paintings, and Madhya Pradesh's tribal sculpture. Only two are paintings—Pattachitra and Thanjavur—while bamboo crafts and tribal sculpture are not paintings.

Options B, C, and D accurately reflect the passage: stepping into Kalagram is likened to another world, Angans are called "living galleries," and thematic zones are inspired by iconic temples like Dakshineshwar Kali Temple and Brahma Mandir.

Therefore, Option 1 incorrectly states four paintings were mentioned, making it the correct answer (as the question asks for the incorrect statement).
