• A. Hypothesis
• B. Forensic Science
• C. Personal Protective Equipment
• D. Experiment

Answer: (D)

An experiment is a study designed to determine the effect one variable has on another by deliberately changing the independent variable and observing the resulting change in the dependent variable while controlling other factors. This deliberate manipulation and control help establish causality, not just association. The other options don’t fit because a hypothesis is a statement you test, forensic science is a field, and personal protective equipment is safety gear.
