Which row in the table correctly compares the relative ionising effects and penetrating abilities of β\betaβ-particles and γ\gammaγ-rays?
| Ionising effect | Penetrating ability | |
|---|---|---|
| A | β \beta\,β greater than γ\gammaγ | β \beta\,β greater than γ\gammaγ |
| B | β \beta\,β greater than γ\gammaγ | β \beta\,β less than γ\gammaγ |
| C | β \beta\,β less than γ\gammaγ | β \beta\,β greater than γ\gammaγ |
| D | β \beta\,β less than γ\gammaγ | β \beta\,β less than γ\gammaγ |
