问题：
| In most cases, you can transplant a tree successfully, at any time, if you follow the instructions for planting a tree. The most important thing is to dig out enough roots, but this process is difficult with a large tree. When you dig out the tree, leave a ball of earth around its roots. This ball of earth should measure about a foot wide for every inch of the tree trunk’s diameter. Dig deep enough to avoid cutting off too many taproots. It is wise to call in a professional tree expert to transplant a tree more than a few inches in trunk diameter. |

A．the less it matters whether you call in a tree expert
B．the more you should avoid cutting off the taproots
C．the larger the ball of earth you must leave around the roots
D．the easier it is to dig out sufficient roots
