一道英语题目,求高手解答一下

code 牛津词典解释为 a set of moral principles or rules of behavior that are generally accepted by society or a social group ,从a set of moral principles( 一套道德规范准则)和accepted by society or a social group ( 用于社会或者社会团体)可以看出符合本句话的意思。而discipline 作为可数名词时,在大学里常常表示学科。或者是a method of training your mind or body ( 一种?方法),和所给句子相差甚远。
