A fishing quota was introduced in an area of sea in 2008. Table shows the mass of breeding fish in the area.
Table
| Year | 2000 | 2005 | 2010 | 2015 | 2020 |
|---|---|---|---|---|---|
| Mass of breeding fish / thousand tonnes | 120 | 80 | 70 | 95 | 130 |
Which conclusion is supported by the data?
The quota caused the mass of breeding fish to rise above its 2000 level
The mass of breeding fish continued to fall after the quota started, then increased
The mass of breeding fish increased by the same amount in each period after 2010
The mass of breeding fish in 2020 was more than double the mass in 2010
