What is the coefficient of x in the expression 2x + 4y?

The correct answer is: 2

The coefficient of x represents the numerical value that is multiplied to the variable x. In this expression, 2 is being multiplied by x, therefore the coefficient of x is 2. The other options, 8, 4, and 0 are incorrect because they do not take into account the variable y and its corresponding value of 4. Option A multiplies the value of y by 4, while options B and D do not have any term that represents x. Thus, option C is the only correct answer for the coefficient of x in the given expression.
