None of these

The correct answer is D. None of these.

Standard time is set at all stations every day at 2:00 AM. This is the time when the clocks are synchronized to the Coordinated Universal Time (UTC). UTC is a time standard that is used as a reference for civil time all over the world. It is based on the Earth’s rotation and is kept in sync with atomic clocks.

The other options are incorrect because they are not the times when standard time is set at all stations every day.
