Solution
The correct options are
A mycorrhiza
D coralloid
Gymnosperms generally have taproots. But, some genera like the Pinus have fungal hyphae growing symbiotically on the roots forming mycorrhiza. This helps the trees to absorb nutrients efficiently. Roots of the trees belonging to the genus Cycas have a symbiotic association with nitrogen-fixing cyanobacteria. Such roots are called coralloid.
