The statement that is true is that positively charged objects attract negatively charged objects. This is due to a law that states 'like forces attract while unlike forces repel. This same concept applies to magnetism. If you put two similar poles together, for example; if you place two south poles together. You feel a separating force between the two poles. But if you place two opposite poles together they attract each other. Hope i helped. <span />
According to fundamental statement about static charges “Like charges repel each other, unlike charges attract each other”. The force between these static charges is called as electric force. Only third option fulfill this criteria. Other options do not satisfy this fundamental statement. Hence, positively charged objects attract negatively charged objects.
