Hint: We know intermolecular forces are electrostatic and include van der Waals forces and hydrogen bonds. Molecules in liquids are held to other molecules by intermolecular interactions, which are weaker than the intramolecular interactions that hold the atoms together within molecules and polyatomic ions.

Complete step by step answer: 
Now we discuss the details of intermolecular forces.
Intermolecular forces: The three major types of intermolecular interactions are,
- Dipole-dipole interactions
- London dispersion forces
- Hydrogen bonds
The interparticle forces in solid hydrogen are the forces of attraction which hold a private molecule together are referred to as intermolecular attractions. In the hydrogens case the attractions are so weak that the molecules need to be cooled to  $ 21K\left( { - 252^\circ C} \right) $  before the attractions are enough to condense the hydrogen as a liquid.
Therefore, option (A) is the correct answer.

Note: In a molecule, when an atom is linked to a highly electronegative atom, it attracts the shared pair of electrons more so it becomes a slightly negative end while the opposite end becomes slightly positive. The negative end of the molecule attracts the positive end of the opposite and as a result, a weak bond is made between them. This bond is named a hydrogen bond.
