Natalie's doctor has just told her that she is going to place two fertilized embryos in Natalie's uterus. Natalie really wants to become pregnant, but she is concerned about the possibility of multiple births. How should Natalie's doctor respond to her concern?
 
  A) The doctor should place more than two fertilized embryos into Natalie's uterus to increase the chances that one will implant.
  B) There is a risk of multiple births with this procedure, and multiple births do present health risks to mothers and babies.
  C) Natalie does not need to be concerned about the possibility of multiple births, because these only rarely result in significant complications for either mothers or babies.
  D) Natalie does not need to be concerned about the possibility of multiple births, because this rarely if ever occurs due to ART.
