What are the genetic factors in obesity is true?

b is the correct answer

there are men and women, some choose to be both or change their gender. often times those people go by "other". those who change their gender are known as "transgender"

age might have something to do with behavior depending on the age because not everyone who is the same age acts the same like 2 year olds could have bad behavior but some won't.

i hope this : )
