Which line from the play shows an example of an allusion?  

“Look at me, my native citizens,”  

“But Niobe was a goddess, born divine—”  

“When I look at her I forget my place.”  

“To be piously devout shows reverence,”

Explanation:

Allusion is an indirect reference to something outside the text. Given that these lines are taken from the play Antigone, the author made an allusion to Niobe, who is not a character in the play, but rather an ancient Greek goddess. 

Having that in mind, the line from the play that shows an example of an allusion is the second choice:

"But Niobe was a goddess, born divine-"

banquo is a great foil
