Both Assertion & Reason are true and the reason is the correct explanation of the assertion.
Commensalism is an interaction in which one species gains an advantage while the other suffers neither harm nor gain. While neither the mango tree nor the whale appear to gain anything, an orchid growing as an epiphyte on a mango branch and barnacles growing on a whale's back do. The classic illustration of commensalism is a cow egret and grazing cattle in close proximity, a scene you are most likely to see if you live in agricultural rural settings. The egrets always feed close to the cattle grazing areas because the cattle's movement stirs up and flushes out insects from the foliage that would otherwise be challenging for the egrets to locate and capture.
Option 1 is the correct answer.
