contrary to other hydrogen halides, hydrogen fluoride is a liquid because

ASize of $$F$$ atom in small
B$$HF$$ is a weak acid
C$$HF$$ molecule are hydrogen bonded
Correct Answer
DFluorine is highly reactive

Solution

$$HF$$ has strong hydrogen bonding, so the force between molecules is stronger for this than in other hydrogen halides.
Hence, $$HF$$ is a liquid at room temperature and other hydrogen halides are gases.
Therefore ,Option C is a correct answer.
