A hard working adult sweats up to 4 gallons per day.
A
Correct answer
Explanation
While the average person sweats 0.5-1 liter per day, athletes or laborers in hot conditions can lose 1-2 liters per hour. In extreme conditions over a full day of intense work, this can reach 8-12 liters (approximately 2-3 gallons). Four gallons is at the upper limit but biologically possible for extreme scenarios, making this claim plausible.
