Why does the advanced age of a mother increase the risk of miscarriage and some birth defects?
 
  a. The new eggs that she produces are more likely to have mutations.
  b. Her eggs, which have aged along with her, are less viable and more prone to mutation.
  c. She is less likely to have the energy to exercise on a regular basis.
  d. Her vaginal cavity is less acidic than when she was younger, allowing weak sperm to impregnate her.
