Which of the following is considered an example of an aquatic invasive species?

The common carp is considered an example of an aquatic invasive species because it is a non-native species that has been shown to disrupt local ecosystems and outcompete native fish species for food and habitat. Originally introduced to various water systems for fishing and ornamental purposes, common carp have proliferated in many aquatic environments where they can negatively impact water quality and the habitats of native organisms. Their feeding habits can uproot native vegetation and stir up sediments, which can lead to increased nutrient levels in the water and promote algal blooms that further harm aquatic ecosystems.

In contrast, rainbow trout, sunfish, and native minnows are generally considered part of the local biodiversity in many regions and interact with ecosystems in a way that supports ecological balance. While certain populations of these species may be raised in hatcheries or stocked in different areas for recreational purposes, they do not typically carry the same invasive characteristics as common carp.
