The Correct Option is C

Solution and Explanation

In endocytic mycorrhiza, fungal hyphae present inside or between the cortex's cells act as biofertilizer. In many kinds of grass and some other crops, the fungal hyphae penetrate the cortical cells, which swell to form vesicles or arbuscules called vesicular-arbuscular mycorrhiza (VAM) and plays a significant role in phosphate nutrition in plants.
