Solution

The correct option is B Mantle
Ectomycorrhizas are further differentiated from other mycorrhizas by the formation of a dense hyphal sheath, known as the mantle, surrounding the root surface. The sheathing mantle can be up to 40 Hm thick, with hyphae extending soil. These associations are formed predominantly on the fine root tips of the host distributed unevenly throughout the root surface.
