In electromagnetism, there can only be interaction between two charged bodies and that the same charges repel and opposite charges attracts. In this item, the words that would best fit in the blanks are that
"... a charged body may body may result to induced charge in the uncharged body. .. the charged body may cause residual charge in the uncharged body.."

The answer is letter C.

The correct answer is C. induced; residual

Explanation:

Going by the law of charges which states that like charges repel and unlike charges attract, we can explain the induction of charges which is one of the methods to charge an object. In the question, it was not stated what kind of charge the charged body has, whether it is positively or negatively charged. However, the induction process can be explained irrespective of the type of charge the initial charged body has. In this explanation, I will assume the charge body is negatively charged.

If a negatively charged body is brought close to an uncharged (neutral) body without touching it will induce polarity on the uncharged body. For sake of clarity, we will refer to the negatively charged body as object 1 and the uncharged body as object 2. The negatively charged body will repel electrons in object 2 closer to it, to the other end of the body thus creating polarity within the uncharged body. There is an excess of positive charge on one side of object 2 and an excess of negative charge on the other side but the overall charge in object 2 remains neutral (the number of protons and electrons remains the same). Then, another charged body which we will now refer to as object 3 is brought in contact with object 2 to ground it. The touching of object 2 by object 3 allows the excess electrons to flow into object 3 leaving a residual positive charges,making object 2 to become positively charged. Upon removal of object 1, object 2 now becomes permanently, positively charged.

The charge received by an object (in this case object 2) is usually opposite to the charge of the object (in this case object 1) that was used to charge it.
