Explanation:
Charging a body refers to the transfer of electric charge to or from the body. There are several ways in which a body can be charged:
1. Rubbing it against another body: When two objects are rubbed together, electrons can be transferred from one object to another. This transfer of electrons leads to one object becoming positively charged, while the other becomes negatively charged. For example, rubbing a plastic comb against a woolen cloth can charge the comb.
2. Touching it to a charged body: When a neutral body comes into contact with a charged body, some of the charge from the charged body can transfer to the neutral body. This results in the neutral body becoming charged with the same type of charge as the charged body. For example, touching a neutral metal object to a positively charged object can result in the metal object becoming positively charged.
3. Bringing a charged body near it: When a charged body is brought close to a neutral body, the charges in the neutral body can be rearranged. This can result in one side of the neutral body becoming positively charged, while the other side becomes negatively charged. For example, bringing a negatively charged balloon close to a neutral wall can cause the wall to become polarized, with one side attracting the balloon and the other side repelling it.
Therefore, all of the above methods - rubbing, touching, and bringing a charged body near another body - can result in the charging of the body. The correct answer is option D.
