B. Surgical sterilization
C. Spermicides
D. Oral contraceptives

Respuesta :

Answer:

C

Explanation:

By itself, spermicide prevents just 72% of pregnancies, the least effective of any major contraceptive measure. Because of its poor success rate, spermicide is often used in conjunction with other contraceptives such as patches and condoms.
