On what do artists mostly make Pattachitra paintings?

Correct answer: On cloth or scroll

The direct answer is A: on cloth or a scroll. Pattachitra is a traditional Indian visual-art form, especially associated with Odisha, in which artists prepare a surface called patta and paint detailed religious, mythological or decorative images on it. The important idea is the prepared cloth or scroll-like surface, not an ordinary modern object. Option A is correct because cloth or a prepared scroll is the traditional support. Option B is wrong because an iron road is not a normal painting surface for this art. Option C is wrong because painting inside a glass bottle is a different craft and is not the usual basis of Pattachitra. Option D is wrong because a plastic toy is not the traditional surface. The word patta is a useful clue, but remember the cultural fact rather than relying only on wordplay: Pattachitra is painted on prepared cloth or a similar scroll surface.
