I don't know that Cl is a gas. Cl2 is a gas, and it is quite reactive.
I chose Cl since the only other possibility is Rn, which, as a noble gas, isn't very reactive. Would Rn be correct, instead?
No, Radon is quite resistant to reaction.
Cl is the best answer, however, Cl2 is chlorine gas. Discuss this with your teacher.
