Answer 2

The sentence that uses syntax for emphasis is option B. "It is easier to do a job right than to explain why you didn't. . Martin Van Buren"

I will provide the explanation: Syntax refers to the word order and the structure of a sentence. In my opinion, in this particular case, the parts of the sentence, "to do a job right" and the "than to explain why you didn't" emphasize the "to do a job right" part.
