Answer: The answer is letter D
Explanation:
Deductive reasoning means having true statements (also called premises) and reaching to a logical conclusions based on them. There is always a logical thought process, where you move from general ideas to more specific ones.
Let's have a look at this example of deductive reasoning:
All apples are fruits. Pink Lady is a type of apple. Therefore, the Pink Lady is a fruit.
The first two sentences are the premises. From those two true statements, the logical conclusion that the Pink Lady apple is a fruit is reached.
In the question, sentence D is an example of deductive reasoning. The first two statements are the true facts that we have (Everyone got an A in Mr. Kims's class and Casey is in that class). Therefore, Casey is getting an A. There's no room for another conclusion. You have reached a conclusion based on true statements.
