Answer:
C. If you like steak and potatoes, you will like this stew.
Step-by-step explanation:
non sequitur is when the conclusion or statement doesn't make sense logically from what was previously stated in the sentence.
"A" makes sense because if he likes to read, he'd also logically like the library since libraries are full of books to read.
"B" makes sense because if she likes fish, she would probably like sushi as well because fish is in sushi.
"C" doesn't make sense because steak and potatoes don't necessarily have anything to do with stew, so if I like one why would I like the other?
hope this helped :)
