Answer:
There are no options, so I will provide a example. An example of a commensalistic relationship would be 'Epiphytes-trees'.
A type of relationship between species of a plant, animal, fungus, etc., in which one lives with, on, or in another without damage to either.
A type of commensalism occurs between little plants known as epiphytes and the huge tree branches they grow on. Epiphytes rely on their hosts for structural support but do not feed on or harm them in any manner.
