B. - the level of material wear is higher

Comment

Short trips with a cold engine usually consume more fuel than driving with a motor in operating temperature. That's why they are particularly harmful to the environment. In addition, the friction is greater in short-distance driving with a cold engine. This leads to a higher material wear.
