Can some one pls help On Morgan’s math quiz, he was asked to simplify the expression 4(3x + 2y + x – 4). His answer was 12x + 8y + 4x – 16. Which best describes Morgan’s error, and what is the correct answer?

A. Morgan used the distributive property correctly, but now he must combine like terms. The correct answer is 24xy – 16.
B. Morgan used the distributive property correctly, but now he must combine like terms. The correct answer is 16x + 8y – 16.
C. Morgan did not use the distributive property correctly because the last term should be positive. The correct answer is 12x + 8y + 4x + 16.
D. Morgan did not use the distributive property correctly because he must factor out the greatest common factor. The correct answer is 2x + y – 2.
