Solution
The correct option is C Apogeotropic
Branch roots are of two kinds long-branching geotropic roots and short-branching apogeotropic roots, which are referred to as coralloid because of their irregular, beady appearance. The coralloid roots contain symbiotic Cyanobacteria (blue-green algae), which fix nitrogen and, in association with root tissues, produce such beneficial amino acids as asparagine and citrulline.
These are apogeotropic in nature (growth or orientation away from the earth; negative geotropism).
