Step-by-step explanation:
The correct answer is a. the fruiting body is tall to allow for spore dispersal, while the hyphae are branched to increase the absorption of nutrients.
In a club fungus, the tall, erect fruiting body (which includes the thick stem and umbrella top-shaped head) is primarily responsible for spore dispersal. The elevated position of the fruiting body helps facilitate the release of spores into the surrounding environment for reproduction and dispersal.
On the other hand, the long, branching hyphae, which are located underground, serve as the fungal network for nutrient absorption. The hyphae extend into the surrounding soil or substrate, increasing the surface area for nutrient uptake from organic matter, decaying plant material, or other sources.
Therefore, the structures of the fruiting body and hyphae in a club fungus are adapted to their respective functions of spore dispersal and nutrient absorption.
