  2. BH−F\mathrm{H}-\mathrm{F}
  3. CH2O\mathrm{H}_2 \mathrm{O}
  4. DCH3COCH3\mathrm{CH}_3 \mathrm{COCH}_3

Correct answer

B. H−F\mathrm{H}-\mathrm{F}

Step-by-step solution

All compound which have hydrogen atom attached to F,O\mathrm{F}, \mathrm{O} or N atom (i.e. highly electronegative atoms) exhibit H bonding. In the question HF exhibit strongest H bonding because F is most electronegative element.
