Chlorine has a valency of 17

In order to complete it's octet i .e.(electronic configuration) it gains one electron to form a negatively charged ion i.e. a anion

E.g. in NaCl sodium has a positive charge of 1(cation)

And chlorine has a negative charge of 1(anion)

 

Hence, option (b) is correct.
