As we have already discussed in Temporary Methods of Birth Control - Oral Contraceptive Pills -

  • These are medicines taken by mouth to help prevent pregnancy.
  • Pills have to be taken daily for 21 days starting within the first five days of the menstrual cycle.
  • After a gap of 7 days (during which menstruation occurs) it has to be repeated.
  • These pills act in four ways:
    • Inhibition of ovulation
    • Inhibition of motility and secretory activity of fallopian tubes
    • Changes in cervical mucus impairing its ability to allow passage and transport of sperm.
    • Alteration in uterine endometrium to make it unsuitable for implantation

Types of Contraceptive Pills:

  • Mini Pills: 
    • They contain progesterone only.
    • Saheli is a non-steroidal pill developed at Central Drug Research Institute (CDRI).
    • It contains centchroman which is taken once a week after an initial intake of twice a week dose for 3 months.
    • These pills primarily act on cervical mucus by making it inhospitable to sperm.
    • These also hinder implantation.
  • Combined Pills:
    • These are most commonly used oral contraceptive pills.
    • They contain both progesterone and estrogen to check ovulation. 
    • Pill Mala D and Mala N are commonly used. They are taken daily without break.
  • Morning After Pills:
    • These are also called the emergency contraceptives.
    • These pills can prevent pregnancy if taken within 72 hours of coitus.
    • They can either suppress ovulation or prevent fertilization.
    • They are most effective in the first 24 hours.
       

 Hence, the correct option is (a).
