Which site is especially famous for prehistoric rock paintings spanning several Stone Age phases?

The Bhimbetka rock shelters in Madhya Pradesh preserve prehistoric paintings and occupation evidence spanning several Stone Age phases. Ajanta, Ellora and Elephanta are primarily historic-period rock-cut religious monuments. Therefore the other options either belong to another chronological phase, a different site, or an older interpretation that does not best fit the evidence. Bhimbetka fits that evidence because it matches the specific chronology, agency and function contained in the question. A comparison with the alternatives is useful: Ajanta, Ellora and Elephanta are genuine historical terms or names, but each belongs to a different office, patron, text, region or sequence. The compact memory link is therefore Bhimbetka together with the factual context above, not the isolated option letter.
