B. better emotional stability

Explanation:

The advantage that the first time parents have in their 20s is that they have a better emotional stability.

This is because their brain is mature enough to understanding the fact that they have become parents and now they need to take care of the baby.

They are physically and mentally stable at this age which helps them becoming better parents.

First time parents in their late 20’s have better emotional stability than first-time teen parents, because teens brains are not fully developed yet, while the brain fully matures for both males and females around the late 20’s.
