The answer is A.
Exercising
excessively is highly discouraged by doctors. This is because it might cause
too much stress on the fetus carried by the mother. Women who are pregnant may
engage in exercise under moderation and should be under the guidance of a
professional. Doctors usually suggest exercises that are safe for both the
mother and the baby. Studies
have shown that exercise contributes to making delivery an easier task because
the muscles of the hip bones are already relaxed.
