Which noun denotes the act of changing something into a different form or use?

• A. Downward trend
• B. Conversion
• C. Replacement
• D. Extension

Answer: (B)

This is about naming the act of changing something into a different form or use. The best word for that is conversion, which means a transformation of form, function, or purpose—like converting currency, converting a file to another format, or converting a room for a different use. The other terms describe different ideas: a downward trend is a fall in numbers over time; replacement is swapping one thing for another; extension is making something longer or broader. So conversion fits the description of a change in form or use.
