Coalesce means to

• A. Grow apart
• B. Unite or merge into a single body, group, or mass
• C. A branch of a society
• D. A graph

Answer: (B)

Coalesce means to come together to form a single unit. It’s used when separate parts merge into one entity, whether liquids joining into a larger drop or ideas, groups, or forces uniting into a single whole. For example, droplets can coalesce into a puddle, or different factions can coalesce into a unified movement. This contrasts with growing apart, which means things are becoming more separate; a branch of a society refers to a subdivision, not the act of merging; and a graph is simply a diagram, not about merging into one body. So the idea captured here is uniting or merging into a single mass or entity.
