Which statement correctly matches a file system to its most common operating system?

• A. APFS is used on macOS.
• B. NTFS is the Windows file system; ext4 is used by Linux; APFS is used by macOS.
• C. NTFS is used on Linux.
• D. ext4 is used on Windows.

Answer: (B)

Matching a file system to the operating system it’s most commonly used with is the key idea. NTFS is the standard Windows file system, ext4 is the typical Linux file system, and APFS is Apple’s file system for macOS (and iOS). This pairing is accurate because each system’s design and features align with that file system: NTFS offers robust permissions and security features used by Windows; ext4 provides journaling, scalability, and reliability favored by Linux distributions; APFS is optimized for Apple devices and SSDs, with features like snapshots and strong encryption. The other statements are incomplete or incorrect: one only mentions macOS without covering Windows and Linux; and others incorrectly swap or assign file systems (for example, Linux with NTFS or Windows with ext4), which doesn’t reflect the common default setups.
