Ionisation potential values of noble gases decrease down the group with increase in atomic size. Xenon forms binary fluorides by the direct reaction of elements. Identify the correct statement$(s)$ from below.

• A
  Only the heavier noble gases form such compounds
• B
  It happens because the noble gases have higher ionisation energies
• C
  It happens because the compounds are formed with electronegative ligands
• D
  Octet of electrons provide the stable arrangements
