C) 85-92% of couples will conceive during the first year

Answer 1

With unprotected intercourse and no means to block conception, the chances of conceiving during the first year are 6-15%.

Step-by-step explanation:

The correct answer is B) 6-15% of couples will conceive during the first year.

According to the information provided, the effectiveness of contraception is generally expressed as the failure rate, which is the percentage of women who become pregnant using a given method during the first year of use. The average one-year pregnancy rate if no contraception is used is 85%. Therefore, with unprotected intercourse and no means to block conception, the chances of conceiving during the first year are 6-15%.

This information demonstrates the importance of using effective birth control methods to prevent unintended pregnancies.
