The correct option is D All of the above
The mode of nutrition in fungi in general is heterotrophic. They are:
1. Saprophytic: They get nutrition from the surrounding organism such as dead organism. The fungi release nutrients for the reuse by the living.
2. Symbiotic: In this relationship the fungi derives benefit from the other organism and also in turn gives benefit. For example a plant in symbiotic association with fungi derives phosphorous uptake due to these fungi.
3. Parasitic: Here the fungi causes serious damage to the host on which it lives.
