Hi there! The answer is D. The quotient of some number and four.
In the algebraic expression we can see a numerator (the x) and a denominator (which is 4). Therefore, we can conclude we are dealing with a fraction. When dealing with a fraction, we divide numbers, this is called a quotient. Hence, we divide a number by four. In other words: our outcome is the quotient of some number and four. Your answer is D.
