Probability sampling involves randomly selecting members from a population, which is exactly what is happening in this scenario. The university is randomly selecting graduates from the population of all graduates who completed their degree two years ago. Statistical inference involves making conclusions about a population based on a sample, but the prompt does not indicate that the university is making any conclusions beyond just studying the selected graduates. Nonprobability sampling involves non-randomly selecting members from a population, which is not the case here. Extrapolation involves extending data beyond the range of observations, but there is no indication that the university is doing this either. Therefore, the best choice is A.
