Why is induced draught considered better than the forced draught?

(a) Because power requirement is high for forced draught

(b) Maintenance of induced draught fan is costlier

(c) Forced draught is less efficient

(d) Forced draught produces less amount of speed of air

This question was addressed to me in an interview for internship.

This intriguing question comes from Cooling Ponds and Towers topic in division Steam Generators & Accessories of Energy Engineering

Correct option is (a) Because power requirement is high for forced draught

The explanation: Induced draught is considered to be better than forced draught because, the power requirement is high for forced draught and the maintenance of fan is costlier. The induced draught occupies less space ass the fan drives are placed at the top of the tower, the cooling effect is distributed across the entire cross section of the tower.
