Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
.msi
Why it's wrong here
The .msi extension denotes a Windows Installer package, which macOS cannot execute natively. macOS installer packages use .pkg, so this option would only be right when deploying software to Windows endpoints through Group Policy or similar tooling.
- ✓
.pkg
Why this is correct
macOS installer packages use the .pkg extension, a bundle format that the Installer application processes to place files and run scripts. This distinguishes it from .dmg disk images and .app application bundles, satisfying the question's requirement for the installer package extension.
- ✗
.exe
Why it's wrong here
.exe is the Windows executable format, which macOS does not use for installer packages. It is tempting because .exe files are commonly downloaded installers, but macOS packages use .pkg or .dmg; .exe would not run natively on macOS without emulation or translation layers.
- ✗
.dmg
Why it's wrong here
.dmg is a macOS disk image used for distributing applications, not the installer package format itself. It is tempting because .dmg files are ubiquitous macOS downloads, but the question asks for the installer package extension, which is .pkg; a .dmg typically contains an app or a .pkg inside.
