Answer: Option (B) is the correct answer.
Explanation:
Elements present in group VII are known as halogens. Elements of group VII are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (As).
Since, they are same group elements so all of them have seven valence electrons.
Whereas inert gases are the gases present in group 8. These are helium, neon, argon, krypton, xenon, and radon.
Active metals are the substances that readily react with another substance. Elements of group 1 are known as active metals as they have only one valence electron.
Therefore, we can conclude that out of the following the halogen elements are all from Group VII.
