The correct conclusion about the interactions is:
The objects in interaction A are farther apart than in interaction B.
In interaction A, where one object has a positive charge (1 C) and the other has a negative charge (–2 C), the force is described as weak, indicating that they might be farther apart. In interaction B, both objects have positive charges (1 C and 2 C), resulting in a strong repulsive force, which suggests that they are closer together.
