Answer:
The formatting of the question is a little strange. I'm assuming these are the four options you're being given:
A) Several different new sports have been invented and some are very dangerous
B) More Baby Boomers are remaining active in their retirement and being injured more often
C) The population in general is increasing, meaning there are more people who can be injured
D) The new equipment used in contact sports is unable to prevent serious injuries from occurring
In this case, B & C are both correct, but B is <em>more </em>correct.
Explanation:
Sports-related injuries are more likely to occur among an active population. Baby boomers are especially susceptible because, according to Jenkins, “Baby boomers still [perform activity] that requires fast movement, such as jumping and landing, or twisting. This means that physical therapists like myself are needed to help to restore proper movement to injured joints, allowing them to remain healthy.” Scott Sailor, president of the National Association of Athletic Trainers (NATA), adds that, “We see this generation being more active: they are participating in tennis, running, triathlons… As long as people recognize the benefits of physical activity, we’ll see them stay active and they will need healthcare providers [like athletic trainers] to assist them with prevention of injury and management of injuries.”
