Our system will evaluate the answer based on this AI-generated description.
The image displays a line graph with speed in kph on the x-axis ranging from 10 to 130 in increments of 10, and nitrogen oxide emissions in (µg/km) on the y-axis ranging from 0 to 45 in increments of 5. There are four lines representing different vehicles: diesel cars with the highest emissions starting at 40, peaking at 42 around 50 kph, decreasing to 30 at 90 kph, rising back up to 35 at 130 kph; petrol cars starting at approximately 10, rising to a peak of 15 at 50 kph, falling to 5 at 90 kph and ending at 10 at 130 kph; lorries beginning at about 35, peaking at around 38 at 50 kph, dropping to 30 at 90 kph, and concluding at 35 at 130 kph; and buses starting at approximately 25, peaking just above 30 at 50 kph, decreasing to around 20 at 90 kph, and finishing at 25 at 130 kph.

The provided line graph illustrates the nitrogen oxide emissions of diesel cars, petrol cars, lorries, and buses at various speeds, nitrogen oxide emissions measured in g/km and speed measured in kilometers per hour. Overall, it is evident that buses exhibit the highest nitrogen oxide emissions.
When starting at 10 kph buses emit 40 g/km, the rate reaches the lowest point when driving at the speed of 60 kph and emits 25 g/km, after that the rates experience a dramatic increase reaching almost 25 g/km at 130 kph. Lorry’s rates followed a similar pattern, starting at almost 35 g/km at 10 kph, then experiencing a decline and falling to almost 15 g/km at 90 kph.
Petrol and diesel cars stay relatively constant throughout the speeds. Diesel cars had the lowest nitrogen oxide emissions among the 4 types of vehicles; beginning at slightly higher than 5 and finishing at exactly 5 at 130 kph. Petrol cars had slightly higher rates compared to diesel cars starting at approximately 10 and finishing at slightly over 10 at 130 kph.
