Which term denotes the act of modifying something so that it better fits one's needs?

• A. Account
• B. Adept
• C. Adaptation
• D. Accumulate

Answer: (C)

The idea here is the act of changing something to fit new needs. Adaptation, as a noun, captures that process or result—the modification itself that makes something suit different conditions or requirements. So it best matches the notion of tailoring something to one’s needs.

For context, to adapt means to adjust or modify, while its related noun adaptation names that adjustment as a thing you do or have done. The other options don’t fit this sense: account refers to a report or explanation, adept describes skill, and accumulate means to gather over time.
