A student tests four different elastic bands, A, B, C and D. She measures the extension of each band for three different forces.
| Force applied in N | Extension of band A in m | Extension of band B in m | Extension of band C in m | Extension of band D in m |
|---|---|---|---|---|
| 2.0 | 0.015 | 0.020 | 0.010 | 0.010 |
| 4.0 | 0.025 | 0.030 | 0.020 | 0.025 |
| 8.0 | 0.045 | 0.040 | 0.040 | 0.060 |
For which band is the extension directly proportional to the force?
Band A
Band C
Band B
Band D
