Correct answer
B. Damage to the gear box.
Explanation
The question is about the effects of an oil leak from a manual gearbox. The effect may be damage to the gearbox - answer B.
The Road Traffic Act requires a vehicle to be built, equipped and maintained so that using it does not endanger people's safety and does not expose anyone to harm. Gearbox oil lubricates the gears, synchronisers and bearings and carries heat away; when there is a leak, the oil level falls, the parts start working with too thin a layer of oil, they overheat and chip, until the gearbox seizes or a gear tooth breaks. The gear ratios (answer A) come from the number of teeth on the gears, and the oil level does not change them. The gearbox temperature after a leak does not fall; it rises (answer C). In addition, leaking oil makes the roadway dirty and can get onto the brake discs - that is why you check for patches under the vehicle at every daily check.
