Adolescent women are most likely to use contraception:

a.
During their first experience of sexual intercourse. My answers is A
b.
If they already have one baby.
c.
If they have been involved in a steady relationship.
d.
If they have just met their sexual partners.

I couldn't find any statistics about this question.

What does your book say?

IT is somewhat curious on c. Research has indicated that teens are more likely than their peers to use contraception when in a steady relationship, unless their partener is more than three years older, in which they are less likely to use effective contraception regularity.

A is most definitely wrong. Passion prevents planning.
D. is most definitely wrong.

Leaving C and b. The problem with b is that many of those babies were the result of not thinking, nor controlling, nor understanding how to use contraception correctly, and consistently. So one mistake does not preclude a second.

c. I vote for c, assuming it means.."f they are involved in a steady relationship with a partner near their age. Research tell us that.

So, make your choice. If I were the teacher, I would have more carefully worded c.

To determine which option is most likely, we can consider the general trends and factors related to contraceptive use among adolescent women.

A. During their first experience of sexual intercourse:
It is less likely that adolescent women will use contraception during their first experience of sexual intercourse. This is often due to lack of knowledge, lack of access, or discomfort discussing contraception. Therefore, option A is less likely.

B. If they already have one baby:
Adolescent women who already have one baby are more likely to use contraception. This is because they may have a better understanding of the importance of family planning and the challenges associated with having another child at a young age. Therefore, option B is a possible answer.

C. If they have been involved in a steady relationship:
Adolescent women who have been involved in a steady relationship are more likely to use contraception. This is because they may have established trust, communication, and a sense of responsibility with their partner, and are more likely to discuss and make decisions about contraception. Therefore, option C is another possible answer.

D. If they have just met their sexual partners:
Adolescent women who have just met their sexual partners are less likely to use contraception. This is because there may be a lack of trust, communication, or knowledge about each other's sexual history, increasing the risk of unintended pregnancies or sexually transmitted infections. Therefore, option D is less likely.

Based on this analysis, options B and C are the most likely answers. Adolescent women who already have one baby (B) or are involved in a steady relationship (C) are more likely to use contraception compared to the other options.
