What does '24' indicate in contraceptives?

  1. 28 days of placebo

  2. 24 active pills and 4 placebo pills

  3. First 24 days are placebo

  4. 24 weeks of contraception

The correct answer is: 24 active pills and 4 placebo pills

In contraceptives, the number '24' generally indicates the number of active pills in a pack. This means that for 24 days, the individual should take a pill containing hormones to prevent pregnancy. The remaining 4 pills in the pack are typically placebo pills and do not contain any active ingredients. The other options are incorrect because they do not accurately reflect the purpose or meaning of the number '24' in contraceptives. Option A suggests 28 days of placebo, which is not the case as most contraceptive pills have a 7-day break where no pills are taken. Option C suggests that the first 24 days are placebo, which would not provide adequate protection against pregnancy. Option D refers to weeks rather than days and is therefore not equivalent to the number '24' in this context.
