Answer:
7.
Step-by-step explanation:
Situational irony is a literary device in which what is expected to happen, the opposite of it happens. It is a form of irony where the actual result differs from what it is expected to be.
Therefore, the given statement, "A contrast between what is expected to happen and what actually happens (the opposite of what was expected)" refers to the situational irony.
Thus option 7 is correct.
