Final answer:
The number of overweight young people has increased 300 percent over the past two decades. The answer is option C.
Step-by-step explanation:
The number of overweight young people has increased 300 percent over the past two decades.
According to studies and data from the U.S. Centers for Disease Control and Prevention, the rate of obesity has been steadily rising since the 1980s. By 2010, nearly 36 percent of adults over 20 years old were obese, and an additional 33 percent were overweight. This means that only about 30 percent of the population was at a healthy weight. The highest levels of obesity are concentrated in the southern states, and there has been a rise in childhood obesity as well.
Hence, the answer is option C.
