Answer:
The correct answer is D.
Explanation:
The word sarcasm comes from Greek where it means 'to tear flesh' or to 'sneer'.
Sarcasm is a sharp and bitter remark, often expressed in a unpleasant manner. It is context-dependent and it is most noticeable in spoken words. It is not an irony as irony is not meant to cause harm, a sarcastic remark may, however, be seen as harmful or as a type of criticism.
The last sentence is sarcastic because of its meaning. A landfill is a place where waste is dumped and located and this is the whole purpose of that place. To indicate that a landfill is filled with waste makes no sense and the words 'it just thrills me' express the speaker's disapproval in form of sarcasm.
