The correct answer is C) Family members can be helpful but also distracting.
What is a true statement about study distractions is that "Family members can be helpful but also distracting."
That is why it is so important to dedicate a fair share of time to family and family activities, and other time to studying activities, in order to have full concentration when you are doing your homework. If you combine the two at the same time, that is when you get so many distractions. So you need to learn to separate both. Indeed, you designate your own private space where you isolated from everything and focus only on school activities.
