Final answer:
The characteristics that enable experiments to support causal statements are a control group, random assignment, and manipulation of the independent variable. The correct option aligning with these characteristics is 1) Control group, random assignment, and manipulation of independent variable.
Step-by-step explanation:
The three characteristics present in experiments that support causal statements are a control group, random assignment, and manipulation of the independent variable. The correct option that includes these characteristics is 1) Control group, random assignment, and manipulation of independent variable. In an experimental setting, these three aspects are crucial to ensure the validity of the experiment and to rule out other factors that might affect the results. The control group serves as a baseline for comparison, random assignment eliminates selection bias and ensures that each participant has an equal chance of being in any group, and by manipulating the independent variable, researchers can observe the effects on the dependent variable, allowing for causal inferences to be made.
