Solution

The correct option is B Add one extra gear in between.
Add one extra gear between the driver and output gears. Adjacent gears on a gear train rotate in opposite directions. So if we want to obtain the same rotation on the desired gear, we have to keep odd number of gears in between the driver and driven gears.
