How can spores of fungi be carried?

Spores of fungi are incredibly versatile and can be carried by multiple means, which makes option B the correct choice. Fungi utilize various transport methods to ensure their spores reach suitable environments for germination and growth.

The wind is one of the most common carriers, allowing spores to travel vast distances through air currents. Additionally, human activity can inadvertently aid in the spread of fungal spores, as they can attach to clothing, equipment, or be moved during agricultural practices. Animals, particularly mammals, can also transport spores on their fur or through feces, contributing to the dispersal process. Water plays a role as well, as spores can be carried by rain, rivers, or other bodies of water, leading to their relocation to different habitats.

Other options fail to capture the full spectrum of spore dispersal mechanisms. For instance, limiting transport to only water does not account for the significant role air and biological vectors play in spore distribution. Similarly, excluding human and larger animal involvement underestimates how widely spores can spread in natural and human-altered environments. Option B encompasses the diverse methods by which fungal spores can move, illustrating their adaptability and importance in the life cycle of fungi.
