Regarding the calculation method for mechanical general ventilation, which of the following is correct? The correct answer is D. (A) When the vapors of several solvents (benzene and its derivatives, alcohols, or acetic acid) are released into a room at the same time, the overall ventilation volume should be set at the maximum value among the ventilation requirements for each of these substances. (B) Volume flow rates should be used when calculating the ventilation balance. (C) Utilizing uncontrolled air inflow can help maintain a positive pressure in rooms where high cleanliness standards are required. (D) In industrial buildings where heat, vapors, and harmful gases are released simultaneously, in addition to local exhaust ventilation, it is advisable to use overall exhaust ventilation from the upper areas; when the room height is greater than 6 meters, the exhaust volume can be calculated at 6 m3/(h·m2)
Is it D? I don’t understand. Could that expert explain it?

(B) Volume flow rates should be used when calculating the ventilation balance. (C) Uncontrolled air inflow can help maintain a positive pressure in rooms where high cleanliness standards are required. (D) In industrial buildings where heat, vapors, and harmful gases are all released simultaneously, in addition to local exhaust ventilation, it is advisable to use overall exhaust ventilation from the upper areas; when the room height is greater than 6 meters, the exhaust volume can be calculated at 6 m3/(h·m2)
D) For industrial buildings that emit heat, steam, and harmful gases simultaneously, in addition to local exhaust ventilation, comprehensive exhaust ventilation from the upper areas is recommended; when the room height is greater than 6 m, the exhaust volume can be calculated at 6 m3/(h·m2)
