Which equation shows a reaction that will occur at room temperature and pressure?

A Br2(aq) + 2NaCl (aq) → 2NaBr(aq) + Cl 2(aq)
B Br2(aq) + 2NaI(aq) → 2NaBr(aq) + I2(aq)
C I2(aq) + 2NaCl (aq) → 2NaI(aq) + Cl 2(aq)
D I2(aq) + 2NaBr(aq) → 2NaI(aq) + Br2(aq)

F2 replaces other halogen ions below it.
Cl2 replaces halogen ions below it.
Br2 replaces halogen ions below it.
I2 replaces halogen ions below it.

So you know A isn't right. Which one is?
