What is the primary purpose of the package main declaration?
- AIt identifies the code as belonging to the main package — the required starting point for an executable program
- BIt imports all standard library packages so they can be used throughout the program
- CIt marks the file as the project's configuration file that controls build settings
- DIt tells the compiler to apply production-level optimizations when building the binary
Why this is the answer
Every executable Go program must have a main package — it marks the entry point; library code uses other names. It doesn't import the standard library (that's import), isn't a build-config file, and sets no optimization flags.
