The correct option is
C Rhodophyta and cyanophyta
Phaeophyta: Chl a, Chl c, fucoxanthin and xanthophyll
Rhodophyta: Chl a, chl d, carotene, phycoerythrin, phycocyannin
Chlorophyta: Chl a, chl b, carotene, xanthophyll
Cyanophyta: Chl a, Chl d,carotene, phycoerythrin, phycocyannin
Xanthophyta: Chla, chl c, carotene.
Euglenophyta: Chla, chl b, carotene.
These are the photsynthetic pigments of different plant groups out of which Rhodophyta and Cyanophyta have similar combinations.
Thus, the correct answer is option C.
