Consider the expression 4x + y + 6z + 12. What are the coefficients in the expression?

Responses
A 1 is the only coefficient.1 is the only coefficient.
B 1, 4, and 6 are coefficients.1, 4, and 6 are coefficients.
C 4 and 6 are the only coefficients.4 and 6 are the only coefficients.
D 1 and 12 are the only coefficients.1 and 12 are the only coefficients.

The coefficients in the expression are 4, 1, and 6. So the correct answer is B.
