Answer:
C.) Circular reasoning: An argument that supports a claim with the claim itself
Step-by-step explanation:
With circular reasoning, a person merely rephrases the conclusion, without proving anything.
You can't prove someone is a 'remarkable' cellist by saying the person is a 'marvelous' musician or 'splendid' performer.
The words 'remarkable', 'marvelous' and 'splendid' are synonyms.
If we could say that Grayson has won many contests as a cellist and performs with best orchestras of the world, that would definitely support the claim that 'Grayson stands out as a remarkable cellist.'
The way the sentence is written is a logical fallacy called 'circular reasoning'.
