The Correct Option is B

Solution and Explanation

Step 1: Understand pavement design
Flexible pavements require methods to assess soil strength and traffic load capacity.
Step 2: Evaluate options
Group Index Method: Used for soil classification, not design.
CBR Method: Measures soil strength (California Bearing Ratio) and is widely used for flexible pavement design.
Triaxial Test: Useful for shear strength, but complex for routine design.
Plate Load Test: Tests bearing capacity, less practical for high-traffic design.
Step 3: Select best method
CBR Method is standard for high-traffic flexible pavements due to its reliability and applicability.
