Professor: A person who can select a beverage from among 50 varieties of cola is less free than one who has only these 5 choices: wine, coffee, apple juice, milk, and water. It is clear, then, that meaningful freedom cannot be measured simply by the number of alternatives available; the extent of the differences among the alternatives is also a relevant factor. The professor's argument proceeds by
A: inferring one general principle from another, more general, principle

C: supporting a general principle by means of an example
D: claiming that whatever holds for each member of a group must hold for the whole group
