The amount of force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. Thus, the strongest interaction would be the one with the highest charge product and the smallest distance. In this case, Interaction B has the highest charge product (+1 x -1 = -1) and the smallest distance (1 unit), so the amount of force between the two objects will be the strongest in Interaction B. Therefore, the correct answer is B.
