select the answer to the problem: d/dx(4) a. 0 b. -5 c. 3 d. -4

Explanation:

Step1: Recall derivative rule

The derivative of a constant $c$ with respect to $x$ is given by $\frac{d}{dx}(c)=0$. Here, $c = 4$ which is a constant.

Step2: Apply the rule

Since 4 is a constant, $\frac{d}{dx}(4)=0$.

Answer:

A. 0
