Answer:
C
Step-by-step explanation:
The sentence that uses the subjunctive mood correctly is C. "The doctor asked that Maria take a few deep breaths to check her lungs." In this sentence, the subjunctive mood is used to express a request, suggestion, or command. The verb "take" is in the present subjunctive form "take" instead of the indicative form "takes." The use of "that" after "asked" also indicates that the sentence is in the subjunctive mood.
