The balloon takes its first sample at a height of 37,000 ft. The second sample is taken 2000 ft higher, which is 39,000 ft. The third sample is taken another 2000 ft higher, which is 41,000 ft. Therefore, the fourth sample is taken at a height of 43,000 ft. The correct answer is C. The first sample is taken at 37,000 ft, then the balloon takes samples at 39,000 ft, 41,000 ft, and 43,000 ft. Therefore, the fourth sample is taken at a height of 43,000 ft, which corresponds to choice C.
