The correct order of boiling points in the following is

Given data : It is given to identify the correct order of boiling points 

Explanation:

A smaller area of contact occurs from the molecule's surface area decreasing as branching increases. This results in a decreased Van der Waals force that can be resisted at a substantially lower temperature. As a result, the boiling point of an alkane chain drops as branching increases.

The boiling point increases as the branching decreases.

Hence, the correct option (B). ${\left(C{H}_2\right)}_{3}CBr < C{H}_{3}CH\left(Br\right)C{H}_{2}C{H}_3 <C{H}_{3}C{H}_{2}C{H}_{2}C{H}_{2}Br$.
