About Letting a bus pull away, a tram stop without a platform, and the bus gate: which statements are correct? (multiple answers possible)

The text explicitly names 'all buses, including touring coaches'.

The rule explicitly applies only within the built-up area.

You may drive a car through a bus gate if there is no bus in sight at that moment.

As long as the bus at the stop is still standing, you may drive on, even when it is already indicating to pull out.

Explanation

The bus is already signalling that it wants to pull away — that is the moment you give way (Book p.92).
