The best option for a random sample of the lamps to be inspected is:
100 lamps on each floor chosen randomly.
This method ensures that each floor is equally represented in the sample, which helps to provide a more accurate estimate of the condition of all the lamps in the hotel. The other options are biased as they do not include a random selection from the entire population of lamps or focus on specific types of rooms without proper representation.
