Solution
The correct option is B Cycas
Coralloid roots are present in the Cycas which contains the symbiotic cyanobacteria also known as blue-green algae. These organisms perform fixation of nitrogen with the help of nitrogenase. This nitrogen fixation produce such beneficial amino acids as asparagine and citrulline for the growth of the plant.Thus, the correct answer is option A.
