The correct answer would be Option B: "Vital national interest", "safer", and "advances". In the text, the author gives an introduction about the subject (nuclear power), then, the good and the bad of nuclear power is discussed, but at the end the author clearly is in favor of using nuclear power, exemplified by the phrase "Other governments around the world justify financing nuclear power plant construction as a vital national interest; we should too." Within the answer options given, option B is the only one that says positive things in regard to nuclear power (which is the author's opinion) therefore is the correct answer. Options A, C and D offer negative views and are not expressing the author's view, therfore they are incorrect.
