Explanation :
The charges can be of two types i.e. positive charge and negative charge. Two materials having the same charges are like charges while two charges having different charges are called, unlike charges.
When two like charges near each other, they repel each other while when two unlike charges brought near each other they attract.
The reason behind the attraction and repulsion between the two charges is electromagnetic interaction.
So, the correct option is (b) "opposites charges attract to each other and like charges repel against each other".
