Correct answer: C
Answer: 1 year — Honda in 2002.
Explanation: Compute year-to-year percentage change for each brand; only one change exceeds 10%.
Honda — 2001→2002: +16.00% (5800 − 5000 = 800; 800/5000 × 100 = 16%). Other Honda changes: 2002→2003: −3.45%, 2003→2004: +5.71%, 2004→2005: +1.35%.
Suzuki — 2001→2002: +3.53%, 2002→2003: −1.14%, 2003→2004: −0.69%, 2004→2005: +1.85%.
Yamaha — 2001→2002: +1.59%, 2002→2003: +4.69%, 2003→2004: +2.99%, 2004→2005: +1.45%.
TVS — 2001→2002: +0.11%, 2002→2003: −3.18%, 2003→2004: −0.59%, 2004→2005: +0.12%.
Bajaj — 2001→2002: +3.64%, 2002→2003: +3.68%, 2003→2004: −4.74%, 2004→2005: +6.57%.
Conclusion: Only the 2001→2002 change for Honda is greater than 10% (16%), so the number of years with an increase greater than 10% for any brand is 1.
