Which word is a synonym for 'to grow or develop gradually'?

• A. Exhale
• B. Evolve
• C. Exhibit
• D. Exclude

Answer: (B)

What you’re looking for is a word that describes gradual change over time. Evolve captures that idea: when something evolves, it grows or develops slowly through a series of stages, becoming more advanced or complete as time passes. The other terms point to different actions—exhale means to breathe out, exhibit means to display or show, and exclude means to leave something or someone out. So evolve is the best fit because it specifically denotes gradual transformation rather than releasing air, showing, or removing. For example, technology often evolves as new ideas build on what came before.
