Answer:

d. The attractive field from the comb is weaker farther from the comb.

Explanation:

In the case of the comb and the piece of papers, the force field created in the comb when the comb was rubbed on piece of cloth was not actually stong enough when the comb was places farther from the piece of paper.

In rubbing the comb on a cloth, a static energy is generated which creates an electric field capable of attracting light objects around it. This field pulls an light object closer to it.
