if i hadn't practiced when i was young",the musician says,"i ___able to play so well now?

A wouldn't be B won't be C wouldn't have been
D couldn't have been.
请选出答案并且
为什么？

选A。
这是虚拟语气，就是把正常的时态再退后一个时间段，就像I hadn't practiced正常时态是I didn't practice，过去时退后一个就是过去完成时；所以，因为后边正常时态为：I won't be able to play so well now，所以退后一个就是A。
其实用排除法也行，C和D是一回事，B是正常时态，不对，所以只能是A。

A B.C都是过去完成时，儿句子中说我“现在”能弹得这么好，所以所以说用现在时态，would在这里只现在时态。

虚拟语气：我就不能弹得这么好，可是现在已经弹好了，和事实相反，时虚拟，用could或者should
