Step-by-step explanation:
The interaction that is considered negative for only one of the species in it, according to the options provided, is predation. In a predation relationship, one organism, the predator, kills and eats another organism, the prey. This interaction is beneficial for the predator but negative for the prey as it results in the prey's death.

Mutualism refers to an interaction where both species benefit, and competition denotes a scenario where both species are negatively affected because they vie for the same resources.
