Option D
Explanation:
Cyanobacteria preserve its photosynthetic pigments in the thylakoids which allows masking of green of chlorophyll a and other accessory pigment i.e phycobiliproteins (phycocyanin, allophycocyanin and phycoerythrin).
Chlorophyll a is mainly responsible for harvesting light for photosynthesis. Phycocyanin is blue in color, allophycocyanin is blue in color and phycoerythrine is red in color. These together harvest light in the green, yellow and orange part of the spectrum which cannot be used by other phytoplankton species
Hence, option D is correct

These rock beds represents the movement or direction of wind and water at the time of deposition and as a result cross beds are formed. So we can say that cross beds were formed due to the direction of wind.
