Answer:
B
Explanation:
A. We saw a scary movie last night on television?
This sentence would be better punctuated with a period, since it doesn't make a lot of sense as a question.
B. That movie was super scary!
This sentence is punctuated properly. The sentence is an exclamation, so an exclamation point is appropriate.
C. When did you see that scary movie!
This has an exclamation point, but it is worded like a question. A question mark would be a better choice here.
D. The movie I saw last night was average!
If the movie was only average, you probably wouldn't want to use an exclamation point. A period would be a better option.
Therefore, B is correct.
