• A. True
• B. False
• C. Sometimes
• D. Uncertain

Answer: (A)

Adaptation is about traits that make an organism more suited to its environment, usually by increasing fitness—the ability to survive and reproduce. When a trait enhances survival or the likelihood of having offspring, individuals bearing it leave more children, and that advantage becomes more common in the next generations. So the idea that adaptation involves changing or increasing fitness to improve chances of survival and produce more offspring reflects the core purpose of adaptation in evolution. It’s also worth noting that adaptation can involve genetic changes across generations or flexible, within‑lifetime adjustments that nonetheless affect fitness. In all cases, the emphasis is on traits that boost reproductive success in a given environment. Therefore, this statement is true.
