Anegatively charged object has a. lost electrons b. gained electrons c. lost protons d. gained protons

A negatively charged object has (b) Gained electrons. Protons reside in the nucleus of atoms and cannot be transferred, so that eliminates choices c and d. Because electrons have a negative charge, gaining more would cause an object to become more negatively charged, while losing electrons would cause the object to lose electronegativity and become more positively charged.
