题目内容：
根据下面资料，回答题 When I was at school, our teacher told the class " You are what you eat．" My friends and I wouldlaugh and call each other "hamburger" (汉堡)and "biscuits"．Our teacher was trying to show us theimportance of eating the right food to stay healthy．
This was 30 years ago when there were big movements to make British people healthier．We startedto eat boiled potatoes instead of French fries and drink fat-free milk instead of whole milk．At first I feltmy potatoes had no taste at all．But after a while I started to prefer healthier food because I felt strongerand I didn't get sick so often．
So we agree that you become what you eat．Do you know what your friends eat just by looking atthem? When you know the effects of different types of food, you can use your knowledge well and eatwhat you want to become．
Food has been so important to our health．Everyone has their own advice to give, which they haveread about or have been told by older people．However, some of these pieces of advice seem to disagreewith each other．For example, some say "Eating chocolate makes you fat," while others say "Chocolatecontains the important minerals (矿物质)like iron and magnesium (镁)．" In fact, what we need tofind out is what type of chocolate to eat and how much of it to eat．
What did the teacher mean by "You are what you eat" in Paragraph 1 ? A．It' s fun to be called hamburger or biscuits．
B．Your life looks like what you eat．
C．It' s important to eat what you like．
