• A. Spleen
• B. Trajectory
• C. Tissue
• D. Toxicology

Answer: (D)

Toxicology is the study of the nature, effects, and detection of chemicals (poisons or drugs) in organisms. It covers how these substances interact with biological systems and cause harm, how the body processes them (absorption, distribution, metabolism, excretion), and how scientists detect and measure them in biological samples. This field underpins medical, forensic, and environmental investigations, helping determine exposure, dose, and potential effects. The other terms listed aren’t fields of study: one is an organ, another is a path or route, and the last is a type of biological tissue, not a discipline.
