So it does not land in the zone of repugnance, a zone which prevents the spores from being consumed by the cow. (zone of repugnance is a zone of which a cow will not eat grass, this explosive dispersal of spores will allow the spores to be eaten by a cow and later pooped out to grow into a beautiful fungus)

Pilobolus or also called as hat-thrower fungus are known for their explosive dispersal. Pilobolus species feed saprobically (living in an environment that is anaerobic, organic-rich matter) on the feces of grazing animals. This microorganism must pass through the grazing animals' digestive tract as part of their life cycle. Because animals avoid grazing near their excreta , this fungi uses a phototropic or light-following squirt-gun mechanism to spread their sporangia up to three meters away from their parent fungus and to the unpolluted vegetation. The ballistic dispersion can reach a speed of up to 90 km/hr. This is accomplished by the release of high-pressure fluids originating from the sporangiophore stalk following the rift of the conspicuous subsporangial vesicle.

Answer:

The correct answer is option C.

Explanation:

The slugs prefer pink flowers over the white ones. Thus, if the slugs are withdrawn from the population, the pink flowers are no more consumed and their number enhances. In a similar manner, the bees like to pollinate more pink flowers in comparison to the white ones.

Thus, again, the pink flowers are getting pollinated in huge concentrations. Thus, the fruits and seeds are set and they produce another generation of pink flowers. Ultimately, there would be more pink flowers in the region in comparison to the white ones as the slugs that used to consume them, are also withdrawn.

Earlier, both the numbers of pink and white flowers would remain steady as even though only some of the bees were pollinating white flowers, they were not getting consumed by the slugs. This had maintained a balance between the number of pink and white flowers. Thus, the number of pink flowers would increase with time if the slugs are removed.
