Decompression sickness (aka "the bends") is caused by rapid decompression in which dissolved gases (primarily nitrogen) come out of solution and form bubbles in the bloodstream and tissues. Hiking in the mountains does not involve exposure to pressurized environments or changes in atmospheric pressure that could cause decompression sickness. The other choices all involve such pressure changes and can potentially cause decompression sickness.
