Which pairing correctly matches tensile strength ranges to the material?

• A. HSS: 39-102 ksi; AHSS: 63-145 ksi
• B. HSS: 63-145 ksi; AHSS: 39-102 ksi
• C. HSS: 10-20 ksi; AHSS: 20-40 ksi
• D. HSS: 150-200 ksi; AHSS: 200-300 ksi

Answer: (B)

The main idea here is to compare the actual tensile strength ranges and match the materials so that the stronger material’s range sits above the other. In this pairing, the High-Strength Steel range is 63–145 ksi and the Advanced High-Strength Steel range is 39–102 ksi. Every bound for HSS is higher than the corresponding bound for AHSS, so HSS is consistently stronger across the chart. That clear, monotonic ordering makes this the best match, because it reflects the intended distinction between the two material families in this context—HSS values are set higher than AHSS values. Other pairings would place the ranges in a reversed or inconsistent way, which doesn’t align with the way the tensile strengths are allocated between HSS and AHSS here.
