A term used to describe something that provides a balance or offset is?

• A. Bacteria
• B. Concave
• C. Chronology
• D. Compensatory

Answer: (D)

Compensatory describes something that provides a balance or offset. It means making up for a deficiency or counterbalancing an effect to maintain equilibrium. In physiology and many fields, compensatory mechanisms adjust conditions to keep things stable when something changes. The other terms don’t fit this sense: bacteria are microorganisms, concave describes a curved surface, and chronology is the order of events in time. So compensatory is the best fit.
