Answer:
Option( A)
The strength of the intermolecular force is Very Strong, because it is a result of interactions between highly polar molecules.
Explanation:
Hydrogen is both electronegative as well as electropositive element. It is an electronegative element which when combines with elements from group 1 or 2, which are metals, can easily take up an electron and when it combines with elements of group 16 or 17 it can lose its electron and form an H+ ion and thus can be considered electropositive.
So, with highly electronegative atoms hydrogen will act as highly electropositive and hence the intermolecular force created will be very strong due to opposite polarity.
