Correct answer

A. Fuel consumption increases
B. Tyre wear increases

Comment

Too low air pressure in the tire as well leads to increased fuel consumption. The effort required to keep the tire running is significantly higher than when the tire pressure has been set correctly. This leads to higher wear on the tire, increased fuel consumption and harms the environment.
