Answer:
A. Matilda loses her beauty because of a falsely beautiful necklace.
Step-by-step explanation:
Irony is defined as a language feature that generates a sense effect that is contrary to the meaning of the word and / or expressions it uses in context to criticize or ridicule the element (or reality) in question. Thus, a term is assertively chosen in order to denote just the opposite of what it means. Irony is also used in literature to mock something that is happening in history. For this reason, we can conclude that an example of irony can be seen in the phrase "Matilda loses her beauty because of a falsely beautiful necklace."
