Final answer:
The statement that a tool modifying program code or manipulating the operating environment is non-invasive is false. A tool that is non-invasive would not make such alterations. A hypothesis is a testable prediction, and in this context, options A and B are hypotheses while option C is a definition.
Step-by-step explanation:
The assertion that a tool that modifies program code or manipulates the operating environment is considered non-invasive is false. Non-invasive tools typically do not alter the program code or operating environment in a perceptible way, rather they observe without causing changes.
In the context of the given options to fulfill a definition of a hypothesis, option A 'Removing invasive species will result in greater biodiversity.' and option B 'Introducing invasive species will harm an ecosystem.' are both examples of hypotheses because they are statements that predict an outcome which can be tested through experimentation or observation. Option C 'Invasive species are non-native species that alter ecosystems.' is a definition rather than a hypothesis, as it does not predict an outcome that can be tested.
