Maggie, Who Just Found Out She Is Four Weeks Pregnant

Maggie, who just found out she is four weeks pregnant, has syphilis. A competent doctor would most likely advise her to

A) have an abortion, as the child will be severely deformed from the disease.
B) take penicillin treatments that will significantly reduce the chances that the syphilis will impact her baby.
C) be prepared for a baby that will be born blind, as she has already passed the point where treatments are effective.
D) not treat the disease until the child is delivered, as the medications used would cross the placental barrier and cause more damage to the unborn child than would the disease itself.
