B) The participation rate was 11% greater in 2010 than in 2000.

This statement is correct because the participation rate increased from 44% to 55%, which is an increase of 11 percentage points. To express this as a percentage increase, we can use the formula:

Percentage increase = (new value - old value) / old value x 100%

Using this formula, we get:

Percentage increase = (55 - 44) / 44 x 100%

= 0.25 x 100%

= 11%

Therefore, the participation rate was 11% greater in 2010 than in 2000. Option B correctly expresses this result.
