The answer is "c".

The usual bird that is discussed is the Cattle Egret.  The grazing cattle do not get any benefit from the insects they stir up.... they are feeding on the grass.  Perhaps indirectly the Egrets cut down on the competitors of the cattle......

Which uses the cattle/birds as an example of commensalism, where one species benefits, and the other is unaffected.
