Which of the following does not serve as a way to neutralize the charge in a body? a. adding free electrons to a positively charged body b. adding more protons to a positively charged body until the number of protons matches the number of electrons c. bringing the charged body into contact with another body having an equal but opposite charge d. allowing free electrons to escape from a negatively charged body

The answer is obviously B. Adding more protons to a positively charged body until the number of protons matches the number of electrons.

Charge neutralization in a body refers to a state in which net charge of particles have been cancelled out by the absorption of an equal number of opposite charges. To sum this definition up, it basically means that, if an object is positively charged, negatively charged ions will be attracted to the positively charged object and the positive ones will be repelled. Over time, it will result in charge neutralization. It makes no sense choosing B. because adding more protons to a positively charged body will only make it more positively charged. Protons must exceed the number of electrons.
