Solution
The correct option is B Annulus
In fungi, both asexual and sexual spores are dispersed by forcible injection. This injection assures the release of spores from the reproductive structure as well as dispersal through the air over long distances. The injection creates tension in the annulus and the elasticity changes. So, we get the spores through annulus. The annulus has radial thickening in the wall which are capable of absorbing and losing water. Annulus controls and assists in spore dispersal by losing water. Annulus also helps in the ejection of spores with force like a sling. Thus the correct answer is option B
