后面的that is cheap and useful是一个定语从句,所以前面缺少一个名词或者代词作定语,我选one,指代前面的a birthday present。

C 你熟悉他们使用的MP4 游戏吗?对不起,我对它不熟悉。 be familiar with 熟悉
be familiar to sb.某人对......熟悉
B the one that is cheap and useful.
在这里做a birthday present的同位that is cheap and useful做定语,是定语从句,that是定语从句中的关系代词,修饰the one意思是又便宜又有用的生日礼物。,the 是定冠词,特指。
