Detailed explanation-1: -Therefore, option a) commensalism is the correct answer.

Detailed explanation-2: -Cattle egrets and the animals they often accompany have a symbiotic relationship. The birds that stand on the backs of bovines pick off parasitic bugs like ticks, fleas and flies while egrets on the ground try to catch grasshoppers or other insects disturbed by the movement of the cattle.

Detailed explanation-3: -The cattle are simply providing for themselves their daily needs, but as a result, they are also providing for a local bird. This is a great example of a commensalism symbiotic relationship; it benefits the needs of one without risk to the other.

Detailed explanation-4: -The interaction between egrets (birds) and grazing cattle is an example of commensalism. Cattle egrets are birds that live near the cattle.

Detailed explanation-5: -There are three basic types of symbiotic relationships: mutualism, commensalism, and parasitism. Mutualism is a relationship in which both organisms benefit. For example, bacteria live in the digestive system of cows. The bacteria help the cows by breaking down plants that the cows eat.
