Answer

Brief Explanations:

In a research question, the independent variable is what is being manipulated or changed to observe its effect on another variable. Here, the number of electrons on the sphere is being varied to see how it affects the magnitude of the electric - field. The size of the sphere and the distance from the sphere are likely held constant (distance is given as 1 meter), and the magnitude of the electric field is the dependent variable.

Answer:

B. Number of electrons
