What is the definition of an “intersection”?

Answer: B — meeting of roads

An "intersection" refers to any place where roads meet or cross. Options A, C, and D all provide definitions that only pertain to a single road rather than the meeting of multiple roads. Therefore, they are not the correct definition of an intersection. Option B is the best choice as it specifically mentions the meeting or crossing of roads, which is the defining characteristic of an intersection. Additionally, the definition of an intersection can include both roads crossing perpendicularly or merging onto one another, which option B covers.
