$$\bullet$$ It is consisting of very few living objects and there is no interaction mentioned about the non-living object, cannot be the ecosystem.
$$\textbf{Option (D):}$$ Earth and its atmosphere
$$\bullet$$ These are inanimate objects, there should be some living objects and their togetherness to form an ecosystem.
$$\textbf{Conclusion:}$$ Hence, the correct option is A.
