An <span>incandescent light bulb is shown in the picture. The filament is the one labelled with number 3. This is a wire made usually of tungsten where the current passes to complete the flow of the electrons from the source to itself as the load. The tungsten material offers a quantity of resistance in ohms. The relationship between the current (I) , resistance (R) and voltage (V) is expressed by the Ohm's Law: V=IR. The voltage across the bulb is directly proportional to the current passing through it with the resistance of the material as its constant of proportionality.
In short, the voltage and current are related through the filament's resistance according to Ohm's Law.</span>

Answer:
b
Explanation:
As we know that
Average velocity= Total displacement/Total time
v=d/t
Average speed= Total distance/Total time
V=S/T
As we know that average acceleration given as
Starting and finishing point is same for race,that means that it total displacement will be zero but total distance will not be zero.So we cam say that it average velocity will be zero but average speed will not be zero.It average acceleration will not be zero also.
So our option b is correct.
