  • A. W and X onlyCorrect
  • B. W and Z only
  • C. X and Z only
  • D. Y and Z only

Chlorine (being electronegative) reacts readily with elements that lose electrons easily. A higher ionization energy means it is harder to lose an electron. Since W and X have the lowest ionization energies in the table, they lose electrons most easily and so react most readily with chlorine.
