As we have learnt, 

Vicinal dihalides, on heating with Zn dust in methanol or ethanol produce alkene.

NaI in acetone can also be used in place of Zn dust.

This reaction is known as Dehalogenation of vicinal dihalides.

Br-CH_2-CH_2-Br+NaI\rightarrow CH_2= CH_2+NaBr+IBr

Therefore, option (1) is correct.
