Answer:
Sarcasm.
Step-by-step explanation:
Sarcasm is a literary device that is used to convey satire and convey the opposite of what one means, usually to humorous effect.
Sarcasm is easier to understand when used verbally as it takes context and voice tone into consideration. The whole idea behind sarcasm is that words are not to be taken literally.
An example of sarcasm is a scenario where someone has a flat tire and a stranger asks, "is that a flat tire you have?"
"No, I just decided to stop here and check the registration number on my tires". A reply like this is an example of sarcasm.
Another example could be if someone complains of being hungry and another replies, "Go and eat"
"Wow, why didn't I think of that before?"
That reply is sarcastic.
