Explosive decompression can cause which of the following conditions?

Explosive decompression primarily leads to a rapid drop in cabin pressure, which can cause serious physiological effects on the body, particularly the lungs. When there is a sudden change in pressure, such as explosive decompression, air trapped in the lungs can expand rapidly, potentially causing lung damage. This condition is known as barotrauma and can result in injuries like pneumothorax (collapsed lung) or other severe respiratory issues.

In this scenario, the other options do not accurately reflect the consequences of explosive decompression. Cabin pressure equalization typically takes time and does not occur instantaneously with explosive decompression, nor does it cause lung damage or improve oxygen levels. Additionally, explosive decompression generally increases panic and stress among passengers rather than decreasing it, as they would likely experience fear and anxiety due to the sudden loss of pressure. Thus, the link between explosive decompression and lung damage is a significant and serious outcome that highlights the danger of such an event in aviation.
