Which quotation is evidence that develops the claim from Part A?

A. “Students, parents, doctors and school officials all need to heed this public-health problem, the group says.” (paragraph 5)

B. “In the same poll, 7 of every 10 parents said they believed their kids did sleep enough. That poll shows too many parents are unaware of the science on teen-sleep needs.” (paragraph 8)

C. “But don’t blame laziness, says Wahlstrom. Or peer pressure, or school demands, or social engagements.” (paragraph 11)

D. “During adolescence, melatonin is secreted later in the day and ramps up at night. This means teens can have trouble if they try to fall asleep before enough of the chemical has been released.” (paragraph 15)
