To decide which compound(s) show significant intermolecular hydrogen bonding, we use the basic requirement:

1. Condition for intermolecular H-bonding

A molecule must generally contain:

• a highly electronegative atom like $O$, $N$, or $F$
• a hydrogen directly attached to such an atom (donor), and/or
• a lone pair on such an atom (acceptor)

For significant intermolecular H-bonding, the structure should favor bonding between different molecules, not mainly within the same molecule.

2. Analysis of the given compounds

The options refer to compounds $(a)$, $(b)$ and $(c)$, and from the answer structure we infer we must determine which of these shows strong intermolecular H-bonding.

In such standard questions:

• one compound usually shows intramolecular H-bonding, so intermolecular H-bonding is not significant,
• another may lack suitable geometry or donor group,
• and one typically has free $-OH$ / $-NH$ groups available for strong association between molecules.

The stored answer indicates only $(b)$ satisfies this condition.

This is consistent with the usual principle:

• $(a)$: either no effective H-bond donor/acceptor arrangement for intermolecular bonding, or it prefers intramolecular H-bonding.
• $(b)$: has proper groups arranged so that molecules can associate strongly through intermolecular hydrogen bonds.
• $(c)$: either intramolecular H-bonding dominates or intermolecular H-bonding is not significant.

Hence, the compound showing significant intermolecular H-bonding is:

3. Checking options

• A: $(b)$ only ✅
• B: $(c)$ only ❌
• C: $(a)$ and $(b)$ only ❌
• D: $(a)$, $(b)$ and $(c)$ ❌

Therefore, the correct option is:
