The function of Core Storage in macOS primarily revolves around handling volume management and logical volume groups. Core Storage is a logical volume manager that allows users to create flexible storage configurations, such as combining multiple physical disks into a single logical volume or creating volumes that can be resized dynamically. This capability enhances storage organization and efficiency, allowing for various configurations like Fusion Drives, where SSDs and HDDs are combined for optimal performance.

While disk encryption is a feature associated with Core Storage, it is not the primary function. Instead, Core Storage natively supports features like FileVault, which manages disk encryption, but its core purpose is volume management.

The standard file system formats are largely provided by the underlying HFS+ or APFS, rather than being specific to Core Storage's role. Additionally, while Core Storage does manage some aspects of mounting volumes, the automatic mounting of external devices is managed by the operating system's broader storage management capabilities rather than something specific to Core Storage. Thus, understanding the primary function of Core Storage as focused on volume management and logical volume groups clarifies why this aspect is the correct answer.
