all lamps from the rooms with king-sized beds

Answer 1

The best option for a random sample of lamps to be inspected is:

100 lamps on each floor chosen randomly.

This method ensures that the sample is representative of the entire hotel's lamp population by including random selections from each of the 30 floors. The other options either focus on specific areas or types of rooms, which may not accurately reflect the condition of all lamps in the hotel.
