Five blocks have the same mass but different base areas. They all rest on a horizontal table. A graph is plotted to show the relationship between the pressure exerted on the table and the base area of the block. Which graph shows this relationship?

1. Apressure against area: straight line through origin with positive gradient
2. Bpressure against area: curve through origin with decreasing positive gradient
3. Cpressure against area: straight line with negative gradient
4. Dpressure against area: curve with decreasing negative gradient
