Answer:
A. Circular
Step-by-step explanation:
Circular reasoning is when people try to argue a statement or point, by beginning with a premise presented as true or an affirmation (In this case, "Toyotas are some of the best-made cars in the world), and instead of proving this point, it simply continues asserting the conclusion, but in another form ("Because they are so well constructed"), as you can see in the sentence, both premises state the same but with different words.
It often follows the following pattern: "A is true because B is true; B is true because A is true.". A point leads to B point, and B point leads to A point, thus making it "circular".
