Step-by-step explanation:
The correct statement about overhead clearance is option a. A vehicle's clearance can change with the load carried.
When a vehicle is loaded with additional weight, it can lower the clearance height. For example, if a truck is carrying a heavy load in the bed, the clearance under bridges or overpasses may be reduced, and the driver needs to be cautious to avoid collisions.
It is important for drivers to be aware of the height of their vehicle and any changes to the clearance due to the load carried, so they can safely navigate under structures without causing damage or accidents.
