The answer is 4. A 25-year-old with a sucking chest wound.
Explanation:
The injured person who must be transported to the hospital in the first instance is the 25-year-old young patient with a chest wound due to suction; since his life, despite being at risk, can be saved. Priority is not given to the 20-year-old, since he does not respond and has a great spinal cord injury, as it is quite chaotic and poor prognosis.
