Solution

The correct option is B $F e (s) + S (s) ⇋ F e S (s)$
In the equilibrium reaction $F e (s) + S (s) ⇋ F e S (s)$ , only solid substances are present.
For these substances, the active mass is considered as unity.

Hence, Le chatelier's principle is not applicable to this reaction.

Therefore, option B is correct.
