In Rhodophyceae, pigments responsible for red colours are-
A
Chl.a, Chl.b, r-Phycoerythrin
B
Chl.a, Chl.d, r-Phycoerythrin
C
Chl.d, r-Phycoerythrin
D
Chl.a, r-Phycoerythrin
Explanation: 

Detailed explanation-1: -So, the correct answer is ‘Phycoerythrin’

Detailed explanation-2: -The members of Rhodophyceae algae have both chlorophyll a&b but they also contain the red colored pigment, phycoerythrin, which in turn causes red color to reflect back in the visible range when light shines on these algae.

Detailed explanation-3: -C) In Rhodophyceae, floridean starch is the stored food and the major pigments are chlorophyll a, d and phycoerythrin.

Detailed explanation-4: -Chlorophyll C is found in red algae, brown algae, and dinoflagellates 15. This has lead to their classification under the Kingdom Chromista 4. Chlorophyll D is a minor pigment found in some red algae, while the rare Chlorophyll E has been found in yellow-green algae.

Detailed explanation-5: -Red algae are a large group of mostly multicellular marine algae. In addition to chlorophyll, red algae contain the pigments phycocyanin and phycoerythrin, which give this group their red coloration.
