Look for flat patches actually used in the artwork.
The painting clearly uses red (dress), green (sari), yellow (skin/ornament), and blue/sky-blue (sari). There is no distinct brown or purple patch among the principal fills (ignoring black outlines and white highlights).
Among the palettes, only (D) contains exactly these four hues without introducing brown/purple.
\[
\therefore \boxed{(D)}.
