Explanation

Why (d) is correct

Leaf pigments can be separated by paper chromatography: each pigment moves a different distance with the solvent.

Why the other options are wrong

(a) · your answer Centrifugation separates cell parts by size and density, not pigments by colour bands.
(b) · your answer Electrophoresis of DNA separates DNA fragments, not pigments.
(c) · your answer Distillation separates liquids by boiling point; it is not used for leaf pigments.

NCERT point: A chromatogram shows that leaf colour is due to several pigments.
