Answer: A

We need to calculate the percentage increase for each car type using the formula: \(\frac{\text{Final Value} - \text{Initial Value}}{\text{Initial Value}} \times 100\).

• A: \(\frac{160-100}{100} \times 100 = 60\)%
• B: \(\frac{200-150}{150} \times 100 = \frac{50}{150} \times 100 \approx 33.33\)%
• C: \(\frac{170-120}{120} \times 100 = \frac{50}{120} \times 100 \approx 41.67\)%
• D: \(\frac{230-180}{180} \times 100 = \frac{50}{180} \times 100 \approx 27.78\)%

The maximum percentage increase is for car type A.
