A Chloride atom has 7 valence electrons (Neutral charge). By gaining an additional election, it can complete its eight valence electrons, and have a charge of -1. Therefore, it becomes an ion by gaining an election, or (a).

A chloride ion has a negative 1 charge. Since chlorine is a non-metal, it forms ions by gaining electrons. In this case, it gains one electron. So (a) is your answer.
