• A

  ${\mathrm{CH}}_4\approx {\mathrm{NH}}_3<{\mathrm{H}}_2\mathrm{O}<\mathrm{HF}$

• B

  ${\mathrm{NH}}_3<{\mathrm{CH}}_4<{\mathrm{H}}_2\mathrm{O}<\mathrm{HF}$

• C

  ${\mathrm{CH}}_4<{\mathrm{NH}}_3<{\mathrm{H}}_2\mathrm{O}<\mathrm{HF}$

• D

  ${\mathrm{CH}}_4<{\mathrm{NH}}_3<\mathrm{HF}<{\mathrm{H}}_2\mathrm{O}$
