B. ChIorophyll a, chlorophyll d and violaxanthin
C.γ Carotene and phycocyanin
D.None of the above

Answer 1

Hint: Brown colored algae has a place with a huge gathering Heterokontophyta, an eukaryotic gathering of living being separated most conspicuously by having chloroplast.

Complete answer:
There are around 1800 types of brown algae, and most are marine. Generally, brown algae are bigger and more species are found in colder waters. For all intents and purposes all the biomass overall originates from a moderately modest number of species in the orders Laminariales and Fucales.
Phaeophyceae individuals are brown algae as yellowish brown colored shades called xanthophylls are dominating. They are generally marine,multicellular and plainly visible in size. They have motile reproductive cells which are pyriform and have two horizontally embedded flagella, one of which is of glitter type. The hold food material is starches, which are constantly put away in a dissolvable state. Chlorophyll a and c are available in phaeophyceae individuals. Fucoxanthin, a sort of xanthophyll, is available in brown algae.

Hence the correct answer is option(A)

Note: Phaeophyceae (Brown colored algae) is a huge gathering of generally marine green growth. The vast majority of the brown algae contain the shade fucoxanthin which is liable for the particular greenish earthy colored shading that gives them their name.
Individuals from a bunch have a characteristic shading that ranges from olive green to different shades of brown, depending on the extent of brown color fucoxanthin to green shade (chlorophyll a and chlorophyll c).
