A Correct answer
Explanation

According to the formula for linear thermal expansion (ΔL = α × L × ΔT), the change in length (ΔL) is directly proportional to the original length (L) of the pipeline. This means longer pipelines will experience more total expansion and contraction than shorter ones for the same temperature change, all else being equal. The coefficient of thermal expansion (α) is a material property.
