A company must keep customers' personally identifiable information (PII) stored within the company's AWS Region. Which governance concept describes this requirement?

Data residency is the correct answer because it refers to the physical or geographic location where an organization stores its data. The requirement to keep PII within a specific AWS Region directly addresses data residency regulations and policies. Data mining is the process of discovering patterns in large data sets, which is unrelated to data storage location. Pre-training bias refers to biases present in the data used to train a machine learning model, not where the data is stored. Geolocation routing is a network routing technique that directs traffic based on the geographic location of the user, which is a different concept from where data is stored.
