Answer:
D. All of these
Step-by-step explanation:
Women in the past used sponges soaked in lemon juice to prevent pregnancy. The citric acid in lemons acts as a natural spermicide. The lemon rind itself (with pulp and juice removed) could be used as a cervical cap. Unripe papaya was used to prevent or terminate pregnancy. ... The seeds of the papaya could actually serve as an effective male contraceptive. Papaya seeds, taken daily, could cut a man's sperm count to zero and was safe for long-term use. The cotton could be seen as a tampon, but was also quite effective as a method of birth control.
