The arrangement of given compound in the increasing order of normal boiling point is Br₂ < CBr₄ < AsBr₃ < CaBr₂.

Norma boiling point of any liquid is that point where the vapor pressure is equal to the standard sea level atmospheric pressure.

And boiling point is directly proportional to the strength of bond which is present between the atoms of any compound.

As we know that ionic bond is the strongest bond and in CaBr₂ ionic bond is present so the boiling point of this compound will be highest.
In AsBr₃, bromine is more electronegative than arsenic and arsenic also have one lone pair on it so some dipole moment develope in it and then this compound will have boiling point less than CaBr₂.
CBr₄ is a covalent compound as in this compound bromine is present which is more electronegative but overall dipole moment of this compound is zero.
Br₂ is also a covalent molecule and it has no dipole moment in it and have minimun boiling point among all compounds.

So, correct order will be Br₂ < CBr₄ < AsBr₃ < CaBr₂.
