I need to ask this question from Types of Ventilation topic in portion Acoustics and Ventilation of Construction & Building Materials

Answer 1

Correct answer is (c) Natural ventilation

For explanation I would say: Natural ventilation is useful for small buildings and it cannot be adopted for big offices, theatres, auditoriums, etc. The only advantage of the system is that it is economical in the sense that no special equipment is necessary for making the room adequately ventilated and that is affords living under natural conditions.
