○ positive and positive

○ negative and negative
○ both positive and positive and negative and negative

Explanation:

First Question (Attraction of Charged Particles)

The fundamental rule of electric charges is that opposite charges attract (positive and negative), and like charges repel (positive - positive, negative - negative). So for attraction, positive and negative charges interact this way.

Like electric charges repel each other. So positive - positive and negative - negative charges will repel. The option "both positive and positive and negative and negative" includes both cases of like - charge repulsion.

Answer:

B. positive and negative
