Answer:
The correct answer is option A, evolution
Step-by-step explanation:
In coevolution, the two or more species that are linked affect the evolution of each other. Coevolution basically has several forms in which one of the form is mutualistic coevolution. In mutualistic coevolution two species interact with each other and they both get benefitted by this association such as the association of algae and fungi in which algae produces food for fungi while the fungi provides raw material to the algae required for food production.
