Answer:
1. In Finding Nemo Dory asks if Marlin is her conscience and he uses a bit of verbal irony in his smart (sarcastic) reply back.
2. In Aladdin, Princess Jasmine was repulsed by Aladdins riches. She uses situational irony as, Aladdins riches did not please her. Aladdin and viewers expected her to fall in love with him for it. This is a situational irony.
3. In The Little Mermaid, it is dramatic irony because Prince Eric does not know that Ariel is the one who saved him due to the loss of her voice. Everyone knows Ariel is the Mermaid except for Prince Eric.
