Lactose,a sugar present in milk, is one of simple sugars used in food preparations for infants.
我认为B 错误,应为 presented. 而NOTES 上认为C错误.

present in milk 是 一个形容词短语 后置修饰名词; 又如 the jobs available to women
这是一个常考结构,one of +限定词+名词C前需加THE
看看这里,偶原来也问过的http://forum.chasedream.com/dispbbs.asp?BoardID=58&ID=61361
sugar 是不可数名词,前面也可以加 a 吗?
难道a sugar是 a kind of sugar 的意思?有没有其他的常出现的例子?
Yes, perfectly right. "present" here means "existing", an adj. "present" has three definitions: n, adj, and v.
"One of the xxxs" should be blurted out.
