Step 1: Understanding the Concept:
We need to match the terms with their correct definitions.
These are related to tractor traction and performance.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the definitions of each term.
Step 3: Detailed Explanation:
Tractive efficiency: Ratio of output power to input power (A-II).
Net traction coefficient: Ratio of net pull produced to dynamic normal load (B-I).
Motion resistance ratio: Rolling resistance force divided by normal load (C-III).
Gross traction: Force calculated from driving torque and effective radius (D-IV).
Thus, the correct matching is A-II, B-I, C-III, D-IV.
Step 4: Final Answer:
The correct matching is A-II, B-I, C-III, D-IV.
Hence, the correct option is (B).
