A system is a part of the <em>physical</em> universe defined <em>arbitrarily</em> for observation purposes.
Boundaries are a part of the <em>physical</em> universe that are around the system.
In a scientific sense, a system is a part of the <em>physical</em> universe whose boundaries, that is, the limit between the system and its surroundings, are defined <em>arbitrarily</em> for observation purposes.
A system contains at least a model, represented in a phenomenological way, and it can be isolated (no mass nor energy interactions), closed (no mass interactions) or open.
The surroundings are a part of the <em>physical</em> universe that are around the system.
An example is a coffee-maker, where coffee-maker the system and air represents the surroundings, the coffee-maker receives energy from a heat source to warm up itself and releases part of such energy to the air.

Answer:
X
Explanation:
Assume your diagram is like the one below.
X represents a mitochondrion.
That's where the Tricarboxylic Acid Cycle converts a single glucose molecule into six molecules of CO₂.
W is wrong. It represents a vacuole, which can store both nutrients and waste products for later elimination.
Y is wrong. It represents the nucleolus, which plays a critical role in the synthesis of ribosomes.
Z is wrong. It represents the cytoplasm, which is where cell processes like glycolysis and protein synthesis take place.
