How to understand the question?

KFC, McDonald’s and Pizza Hut… These fast food restaurants constantly remind us of the American fondness with hamburgers, chips and pizza. But America’s reputation as the home of fast food is under threat from the British, according to research carried out by the BBC in 13 nations among 9,000 people. Though they are afraid of putting on weight, the study found the British are more interested in junk food than any other nation. Almost half of British respondents (?????) said they enjoyed fast food too much to give it up. About 44 percent in the US claimed they would be unable to stop eating burgers, pizzas and chicken wings, making the country second in the world’s junk food league. The third place went to the United Arab Emirates, where 35 percent are junk-food lovers. The research also found that attitudes to food and weight vary wildly around the world. Those in the UK and US believed lack of self-discipline (??) was the main factor behind growing waistlines. They can’t deny themselves hamburger or extra piece of pizza, but “make themselves feel better by washing it down with a diet coke”, the study suggested.The French, on the other hand, seem to keep a watchful eye on their weight. They get on the scales every day. Only 19 percent of the French surveyed admitted a fondness for fast food. It is said that the French valued the combination of good food and company. Sharing classic food and time with loved ones is the key to the French sensibility. “French people take care of their image as a matter of course. Being thin is part of our culture and a point of pride. We are known for it,” said Thierry Pailleux. The research suggests that _____________. A. Americans love fast food and are proud of the fast food they eat B. those British who love fast food do not care about their body weightC. the British would like to think that other food they eat make up for eating occasional fast food D. most people love fast food as they don’t think such food will lead to their growing waistlinesThe key is "C". But I can't find the basis in the jpassage. Can you help me? Thanks.
