Concept: Percentage growth over the previous year is calculated as ((Value this year − Value last year) ÷ Value last year) × 100. To find the year in which PCV's growth outpaced every other segment, this growth rate must be worked out for CV, PCV, and TW in each year and compared WITHIN that same year — not compared against PCV's own growth figures in other years.

Application: Reading the CV, PCV and TW bars for each year from the graph and applying the formula above gives the following year-on-year growth rates:

Comparing across each row: in 2004 and 2007, CV grew faster than PCV; in 2005 and 2006, TW grew faster than PCV. Only in the 2008 row does PCV's growth rate exceed both CV's and TW's growth rates for that same year.

Cross-check: PCV's own growth was numerically largest in 2004 (about 14.81% over 2003) — which is why 2004 looks tempting, except 2004 is not one of the listed choices. But the question does not ask for the year of PCV's own peak growth; it asks for the year in which PCV grew faster than the OTHER segments in that same year. Checking that stricter condition year by year — CV led in 2004 and 2007, and TW led in 2005 and 2006 — leaves exactly one year where PCV is ahead of both other segments, confirming the result above.

Hence, the year during which the percentage sales growth of PCVs over the previous year was the highest among all segments is 2008.
