Hint: In this question we have to state that the formation ammonia in done from ${H_2}$ and ${N_2}$ by the well known process named as Haber’s process with using the $Fe$ is the example of which of the above given option. As we all know the mechanism of Haber’s process we can easily justify the answer.
Complete step by step solution:
As we all know, The Haber process involves interacting atmospheric nitrogen ${N_2}$ with hydrogen ${H_2}$to produce ammonia $N{H_3}$ . High temperatures and pressures are maintained while a metal catalyst is used in this process. Nitrogen is supplied by air.
${N_2} + 3{H_2}\xrightarrow{{}}2N{H_3}$
As we mentioned above the full data of Haber’s process. Now In this we get, ${H_2}$ and ${N_2}$ are reacted with each other to form the liquid Ammonia nut as given in the question we have to $Fe$ with it. From which the state of ammonia is in liquid form but the state of $Fe$ is in solid state.
As from this we can say that, the $Fe$ is in solid state and the reactant present in left are as in the gaseous state as by cooling them the ammonia turns in the liquid state as like a hetero mixture.
Catalysis that is heterogeneous occurs when the catalyst does not take part in the reaction that it is enhancing.
From taking the whole conclusion we can say that this is an example of Heterogeneous catalysis.
Therefore, the correct answer is Heterogeneous catalysis.

Hence, the correct option is (A)

Note: Now we are going to discuss some important topics of this question. Homogeneous catalysis is defined as catalysis in which the reactants and catalyst are in the same phase, or the same physical condition. A type of catalysis in which the reactants and catalyst are in the same phase. The same physical state is referred to as heterogeneous catalysis.
