Which description matches 'merge'?

• A. To separate into parts
• B. To put two or more things together; to unite; to combine
• C. To begin a project independently
• D. To dissolve in water

Answer: (B)

Merge means to bring two or more things together into a single unit. This captures the idea of uniting or combining, which is exactly what the description conveys. For example, when two companies merge, they combine into one organization. The other options describe opposite or unrelated ideas: separating into parts is the opposite of merging, starting a project independently implies acting alone, and dissolving in water describes a chemical change rather than joining.
