Step-by-step explanation
When a candidate is aspiring to a public administration position in politics such as the presidency, the senate or similar, it is of great importance that they expose their background because it will allow voters to know the experience of this candidate to perform adequately in the position to which you are aspiring. On the other hand, this is important since voters will know if the candidate has committed prohibited acts such as corruption. Therefore, the correct answer is B. Because background checks are carried out by voters to verify the character of the candidates.
