Strategy:
 Electronegativity () decreases down a group and generally increases across a period. Use specific values or positions in the periodic table to rank the elements.

Step 1: Locate elements and check EN values
- Fluorine/Bromine (Group 17):  has high  ().
- Carbon (Group 14):  is .
- Phosphorus (Group 15):  is .
- Astatine (Group 17):  is .

Step 2: Determine order
Given its halogen nature,  is the most electronegative. Carbon (Period 2) is more electronegative than Phosphorus (Period 3)
