Correct answer
CBr>C>At>P

Step-by-step explanation

On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the bottom left.

Element             Electronegativity

P                         2.1

C                           2.5

Br                          3.0                   

At                           2.2

Hence, the correct order is Br > C > At > P.
