D Correct answer
Explanation

Track modulus is the technical term for the measure of track stiffness - it quantifies the load required to produce a unit depression in the track. Tractive force (option A) relates to pulling power, load capacity (option B) is maximum load bearing, and gauge (option C) is the distance between rails.
