Explanation:

Step1: Locate the wolf - population curve on the graph.

The wolf - population curve is one of the two curves shown in the graph.

Step2: Identify the peak value of the wolf - population curve.

By observing the graph, we find the highest point on the wolf - population curve.

Step3: Read the corresponding value on the y - axis.

The y - axis represents the population size. Reading the value at the peak of the wolf - population curve, we see it is around 170.

Answer:

C. 170
