A body can be negatively charged by:
A. Removing some neutrons from it
B. Giving excess electrons to it
C. Removing some protons from it
D. Removing some electrons from it

Hint: Charging is an attribute of the body. It comes under electrical friction. Losing surplus electrons results in a positive charge. You can take an experiment in your day to day life example to understand this concept. Lodestone or amber. Donors are going to be positive and acceptors are going to be negative.

Complete solution:
1.Gaining a charge is a property of an object or body. The electrical charge, when they are rubbed together, is positive or negative, created on objects.
2.Take a scale and a piece of paper as an example. The paper pieces are attracted to the scale when scales are rubbed on the hair and held near the piece of paper.
3.It implies that both have some sort of charge. We know that some electrons from the atoms on the surface of one are removed and transferred to another when two substances are rubbed together.
4.The body that gains electrons is charged negatively and the other that loses electrons is charged positively.
5. So there are basically two kinds of electrical charges, one positive and one negative. If it gains excess electrons or gives them excess electrons, an object is negatively charged and otherwise positively charged if it loses or is uncharged with excess electrons.

Hence, the correct option is (B).

Note:
Electric charges will not be generated or destroyed, but they can be transferred to another part of the substance from one part of the substance or system. So the total charge of an isolated system remains constant in an isolated system.
