Correct option is B)

  • Fluorine is the most electronegative element because it has 5 electrons in it's 2p shell. The optimal electron configuration of the 2p orbital contains 6 electrons, so since Fluorine is so close to ideal electron configuration, the electrons are held very tightly to the nucleus.
  • Hence option B is correct answer.
