Grammar

[contiluo]

I am confused with the grammar rule. Which of the following option is acceptable?

My sisiter is a college student. She is usually a little busier than ___________.

(1) me (2) I (3) I am :up:

 

[Tdol]

You will see all three being used. Traditional grammars tended to favour I, but me has a long history of usage. In formal language, it might be safer to use I.
