The correct answer is A) Changing while growing.
What accurately describes development is changing while growing.
That is how you develop. Throughout time, in different moments of your life, your body is having major changes and transformations. These are biological and chemical transformations, according to your age. These changes allow you to develop new things, sensations, emotions, thoughts, and actions. If you remember well, what you like when you were a child, it is so different than what you like or thinks now that you are an adolescent. That is how you develop through changing.
