Because the question requires the user to make assuptions about how the end user's systems are configured which are defined in the question.
In this case we don't know and have to infer
what the timezone of the users PC is set to
What language settings are set on the user's PC - specifically date formats
what the timezone of the user's server with SQL server installed is set to
What language settings are set on the user's server with SQL server installed - specifically date formats
What language settings are set on the SQL server instance.
If these differ from the questioner's setup then the correct answer is probably 'None of the above' which is not an option.
Any question needs to ensure all information to answer it is provided and not need the answerer to make assumptions.
In this case that could have been as simple as saying a default installation of MS Windows and SQL server for whichever region has that timezone (its not the only one with fractional hour offsets though).
