A negatively charged object is an object that has more electrons than protons. This creates a negative electric charge on the object. Option A is incorrect because this would cause a neutral electric charge, as protons and electrons have equal and opposite charges. Option B is also incorrect because this would also result in a neutral electric charge. Option D is incorrect because neutrons do not have a charge, therefore an object made up of only neutrons would not have an electric charge.
