The mother of a 9-month-old infant is concerned that the head circumference of her baby is greater than the chest circumference. The best response by the nurse is:
 
  a. This is normal until the age of 1 year, and then the chest will be greater.
  b. Perhaps your baby was small for gestational age or premature.
  c. Let me ask you a few questions, and perhaps we can figure out the cause of this difference.
  d. These circumferences normally are the same, but in some babies this just differs.
