Which situation best represents a commensalism relationship?
A
both organisms benefit
B
one benefits while the other is unaffected
C
one benefits while the other is harmed
D
neither organism benefits
Explanation: 

Detailed explanation-1: -Commensalism is when one organism benefits and the other is left unharmed, and mutualism is when both organisms benefit from the interaction.

Detailed explanation-2: -Commensalism is another type of symbiotic relationship where one organism benefits and the other organism isn’t benefited or harmed either way. Golden jackals will follow tigers on their hunt for prey so that they can feed off of the tiger’s scraps.

Detailed explanation-3: -One of the best-known examples of a commensal is the remora (family Echineidae) that rides attached to sharks and other fishes. Remoras have evolved on the top of their heads a flat oval sucking disk structure that adheres to the bodies of their hosts.

Detailed explanation-4: -The simplest example of commensalism is a bird making a nest in a tree. The tree provides shelter and protection to the bird without getting significantly harmed or affected by the bird. Another typical example is the cattle egrets (birds) that feed upon the insects stirred up by the feeding cattle.
