Question

Quizplus · Accepted Answer

Sentence B is correct because it uses "which" with commas to introduce a non-restrictive clause, providing extra information about the tugboat without limiting the scope of what is being discussed. "That" in sentence A is used for restrictive clauses (which define or restrict the subject) and typically does not require commas. "Who" in sentence C is incorrect because it is used for people, not objects like tugboats.
