MLA in-line citation, sentence ends with quotation?

[Mika]

I'm not sure where the citation goes:

According to the Institute of Medicine, “there is no evidence that marijuana serves as a stepping stone on the basis of its particular physiological effect.” (Lowry 180)

Should it be after the period but before the quotation mark? Or just like it is above?

[The Now Mrs. H]

Like it is above, but move the period.

According to the Institute of Medicine, “there is no evidence that marijuana serves as a stepping stone on the basis of its particular physiological effect” (Lowry 180).

If you have an exclamation point or a question mark, you would do this

According to the Institute of Medicine, “there is no evidence that marijuana serves as a stepping stone on the basis of its particular physiological effect?” (Lowry 180).
