Solution

The correct option is B Increase from carbon to fluorine.
Electronegativity is a measure of an atom's ability to attract shared electrons to itself. On the periodic table, electronegativity generally increases as you move from left to right across a period due to increase in effective nuclear charge.
Therefore, electronegativity increases from carbon to fluorine.
