Hint: Orchids make one of the two largest families of flowering plants. These include around 28,000 known species to date. The majority of orchids grow anchored on tree branches. They show a symbiotic relationship where plants neither get benefitted nor get harmed.

Complete answer: Orchids are flowering plant families having a large group of colorful and fragrant flowers. Orchids are found in tropics or subtropics. They grow anchored on the branches of trees or shrubs. Some of the orchids are terrestrial and are found in grassland habitats. Orchids show a symbiotic relationship with trees in which they get their nutrition from them. This is a healthy relationship in which no harm is done to the trees and there is no benefit to trees from Orchids. Such a type of symbiotic relationship is called Commensalism. It is a long term association as orchids obtain their nutrients, shelter, and support from the trees. Usually, commensalism occurs between large hosts and small communal species. Such a type of symbiosis is evident between suckerfish and sharks. The suckerfish rides by staying attached to sharkskin.
Orchids are known for their scent which is frequently used in making perfumes. Orchid cultivation is done as they are considered flowers of enjoyment. Vanilla is a genus of Orchids and is used as a flavoring substance in many cuisines. Orchids also have many cultural symbolism values.
So, from the above discussion, we can conclude that the right answer is option B.

Note: Commensalism term is derived from the words ‘commensal.’ This means “eating at the same table.” It is thought that dogs earlier benefitted from the human camps and showed commensalism with humans. Later the bond became social and led to a domestic relationship between the two.
