Which of the following describes a relationship of predator-prey

I couldn't find the options to answer this question online, but I'll give you an explanation so you can answer it yourself.

Predator-Prey relationships occur in nature where one species hunts the other to feed on it. In this case, the hunter is the predator, who will kill the prey after stalking it in order to feed.
