the strongest intermolecular forces present in a pure ch4 sample are...
ion - dipole forces
london dispersion forces
dipole - dipole forces
hydrogen bonding
lonic bonding

Explanation:

Methane ($CH_4$) is a non - polar molecule. Ion - dipole forces require ions and polar molecules. Dipole - dipole forces occur between polar molecules. Hydrogen bonding requires hydrogen bonded to highly electronegative atoms like N, O, F. Ionic bonding is between ions. London dispersion forces are present in all molecules and are the only intermolecular forces in non - polar molecules like $CH_4$.

Answer:

B. London dispersion forces
