As a Nurse Assesses an Elderly Patient,answers Seem Vague or Unrelated

As a nurse assesses an elderly patient,answers seem vague or unrelated to the questions.The patient also leans forward and frowns,listening intently to the nurse.An appropriate question for the nurse to ask would be:

A) "Are you having difficulty hearing when I speak?"
B) "I notice you frowning.Are you feeling annoyed with me?"
C) "How can I make this assessment interview easier for you?"
D) "You're having trouble focusing on what I'm saying.What is distracting you?"
