Which choice completes the text so that it conforms to the conventions of Standard English?

  • A. patients
  • B. patient's
  • C. patients'
  • D. those of patients

Correct Answer: C

Explanation:

C. A possessive is required that will express the idea of the problems of patients, where patients is plural. Choice A isn't possessive. Choice D incorrectly uses both “those of” and “problems,” which are illogical when combined. Choice B incorrectly expresses the problems of one patient. Choice C is the best answer.
