Correct Answer:
A. More number of TO
Explanation:
In railway logistics, Pre-Detention Delay (PDD) refers to the time a wagon spends waiting before being processed or moved. A high PDD signifies that wagons are remaining idle for longer periods, which directly reduces the frequency of trips a wagon can complete. Consequently, an increase in PDD leads to a higher number of turnovers (TO) because the overall cycle time for each wagon is extended, resulting in more frequent cycles through the system to meet transport demands.
