Answer 1

The correct option is D increasing its resistance to Insects.

Mycorrhiza helps the host plant in enhancing its phosphorus uptake capacity, in increasing its tolerance to drought. Mycorrhiza produces some chemicals which resist the pathogen like Fusarium.

So, the correct option is 'increasing its resistance to insects'
