You can access the info or options assets both in editor and at runtime. Below is how you achieve this for both assets:
In the editor, you can access both via the UtilEditor class. Which contains properties for Build Information & Build Options ****to access both assets:
public void ExampleMethod()
{
var info = UtilEditor.BuildInformation;
}
At runtime you need to use the AssetAccessor helper class and get the relevant asset via the GetAsset<T>() method like so:
public void ExampleMethod()
{
var info = AssetAccessor.GetAsset<BuildInformation>();
}
