A patient has just been diagnosed with pernicious anemia. The patient asks the nurse why his body is not able to absorb vitamin B12. The nurse responds,
 
  A)
  You have too many ulcers in your stomach.
  B)
  More than likely, you were born with deficient vitamin B12 stores.
  C)
  Your stomach is not secreting a substance known as intrinsic factor, which is needed to absorb vitamin B12.
  D)
  Your daily intake of high saturated fats is interfering with the stomach's ability to absorb the nutrients that it needs, especially vitamin B12.
