D Correct answer
Explanation

Electronegativity increases across a period and within a group. The correct increasing order is carbon (2.55) < nitrogen (3.04) < oxygen (3.44) < fluorine (3.98), which is the most electronegative element. Fluorine has the highest electronegativity value of all elements.
