Thirteen-Year-Old Chris, Who Has a 6'2" Father and a 5'1

Multiple Choice

Thirteen-year-old Chris, who has a 6'2" father and a 5'1" mother, is worried because he is only as tall as his mother right now and would like to be much taller. What would you tell Chris if he confided his concerns to you?

A) "Sorry, Chris, but you've probably already reached your mature height. Just remember, many great men were short. Think of Napoleon!"
B) "Don't worry Chris. Most boys don't reach their full height until they are 17. You've got about four more years to grow and you are likely to be of average height because you have a tall father and a short mother."
C) "You should go to the doctor, Chris. You are abnormally short for your age and parents' heights. You may have a growth hormone deficiency."
D) "You don't have anything to worry about, Chris. Most boys end up being taller than their mothers and fathers, so you will probably be over 6'2" before you stop growing."
