The percentage decline in exports during the period 2006-2011 is more than the percentage decline in exports during 2012-2017 by approximately

Percentage decline during 2006-2011 period $=\frac{\text{Difference between 2006 and 2011 exports}}{\text{2006 exports}}\times100$

$=\frac{280-220}{280}\times100=\frac{60}{280}\times100=\text{approximately }21.42$%

Now, percentage decline during 2012-2017 period will be calculated similarly.

$=\frac{210=200}{210}\times100=\frac{10}{210}\times100=\text{approximately } 4.76$%

As we can see, the first percentage is more than the second by approximately $16.5$, hence Option 1 is the answer.
