Solution
The correct option is B Earth
Eartha mimics the Earth's movements inside a weatherproof three-story glass atrium at Delorme mounted on a custom-designed, mechanized cantilever arm.
Eartha is tilted on a 23.5 degree axis, mimicking the real Earth's angle. The surface is composed of 792 panels printed from a computerized database and incorporating shaded relief and depth info, roadways and cities. According to DeLorme, it's the largest Earth image ever created.
Eartha takes 18 leisurely minutes to make a complete cycle, a speed that ensures that even the smallest visitor won't get sucked into her orbit. But Eartha can also reportedly be accelerated to a speed that zips though an entire Earth year in 60 seconds.
