Answer:

(C) CBr₄

Explanation:

The compound CCl₄ has one carbon atom (group 14) and 4 chlorine atoms (halogens). On the basis of the periodic properties, other 4 halogens bonded to carbon would also present nonflammable properties like those of CCl₄ -and thus they could be used as a fire-resistant chemical-, that's why the answer is C) CBr₄
