Which of the following sentences is grammatically correct?

  • A. The patient and the nurse knew he could walk.
  • B. While the patient was walking.
  • C. The patient, the nurse, and the doctor were walking.
  • D. Because the patient could walk, he was allowed to leave his room.
Correct Answer: D

Rationale: The correct answer is D. This sentence is grammatically correct as it uses the conjunction 'because' to connect two clauses properly. 'Because the patient could walk' is a dependent clause, and 'he was allowed to leave his room' is an independent clause. Option A is incorrect because it lacks a conjunction to connect the two subjects correctly. Option B is a sentence fragment without a main clause. Option C is incorrect due to the misuse of commas to separate the subjects; it should use 'and' to list the subjects properly. Therefore, Option D is the only grammatically correct sentence among the choices.
