Which of the following statements correctly accounts for the general increase in electronegativity across a period from left to right in the periodic table?

A) The number of inner shielding electrons increases significantly, pushing shared electrons further away.

B) The effective nuclear charge increases while the principal energy level remains the same, attracting shared electrons more strongly.

C) The atomic radius increases across the period, allowing the nucleus to interact more directly with bonding pairs.

D) The addition of new electron shells weakens the electrostatic repulsion between bonding electrons.
