Answer:
Both organism A and B get benifit.
Explanation:
Mutualism is an association of two organisms of different species in which both the organisms get benefit from the association or relationship.
For example, let’s say organism A is bee and organism B is the flower. A bee visits flower to flower to collect nectar for its food. While bee visiting flower to flower, it pollinates the flower.
Thus, the bee gets food from this association and in return, flowers are pollinated. Thus both organism A and B get benifit.
