The correct option is D Cycas
Roots in Cycas are of two types- normal and coralloid roots. Coralloid roots are irregular, negatively geotropic (stems grow away from the ground in the opposite direction of gravitational force), dichotomously branched coral-like roots that do not possess root hair or root caps. Coralloid roots have a symbiotic association with blue-green algae like Nostoc and Anabaena species that help in these plants' nitrogen fixation.
Sequoia has a tap root system, which is a common feature of gymnosperms.
Pinus and Cedrus have roots with a fungal association called mycorrhiza, a symbiotic association between the plant and the fungus.
