The lateral displacement is I don’t know tbh I think 16.8
It is c which is four minutes per day
For A: LED outdoor lighting.
Because you want it to be able to withstand outdoor conditions. If it can’t withstand... there’s no light... no light... no advertisement.
For B: it would be lithonium lights. It’s found in most offices and gives the best light for working day or night.
For C: you’ll want elevated lights so they are noticed for the plane to land and for people and others to see.
For D: you want white light and you want it to also be able to withstand outdoor conditions. Cars and people need to see at night, especially at night. Solar would be a great choice.
Hope this helps! I tried hard.
