The correct answer is: LiF
The electronegativity of halogen is as :
\(\mathrm{F} \gt \mathrm{Cl} \gt \mathrm{Br} \gt \mathrm{I}\)
Among alkali metals the electropositive character increases as :
\(\mathrm{Li} \lt \mathrm{Na} \lt \mathrm{K} \lt \mathrm{Rb} \lt \mathrm{Cs}\)
Hence, LiF is the most stable compound.
