71st BPSC

Show answer and explanation

Correct answer: (d) Increased mineral absorption and diseases protection

Explanation

Mycorrhiza is a symbiotic association between fungi and plant roots, with fungal threads extending into the soil.

The plant gains increased mineral absorption (especially phosphorus) and better water uptake.

It also gets protection against soil-borne pathogens and diseases, so both benefits apply together.
