Why recommendation of fixed ratio gears done for top mounted equipment

1.	Why recommendation of fixed ratio gears done for top mounted equipment?(a) Because they are easy install(b) Requires less space(c) Due to its low cost(d) Because of their high efficiencyThis question was addressed to me during a job interview.Question is from Components of Wind Energy Conversion System in section Wind Energy of Energy Engineering
Answer» Right answer is (d) Because of their high EFFICIENCY The best explanation: Fixed ratio GEARS are recommended for TOP mounted equipment because of their high efficiency, and minimum system risk. For bottom mounted equipment requiring a right angle drive transmission costs can be reduced on the HUB by increasing ROTOR speed to generator.
