What type of relationship is the most beneficial to both of the organisms involved?A) Commensalism B) Mutualism C) Parasitism D) Symbiosis

B) Mutualism

Symbiosis is a
close relationship between organisms of different species in which
ONE or BOTH the organisms
benefit. Symbiotic relationship has three types: Parasitism, Mutualism and
Commensalism

Parasitism is a kind of relationship in which
one species benefits while the other is harmed.  On the other hand,
MUTUALISM, is the type of relationship in which BOTH
organisms benefit. An example of this is the pollination of flowers by bees. As bees get
nectar they also help the flowers pollinate. Lastly, commensalism is the relationship in
which one organism benefits and the other organism is neither helped nor
harm.
