【正确答案】：C
【题目解析】：Extension of meaning is also found in many technical terms, which as the term suggests are confined to specialized use. For instance, alibi, a legal term signifying ‘ plea that the accused is not at the place when the crime is committed’，has now come into common use，meaning ‘excuse’.许多意义有专指的技术术语中也有词义扩大的现象。比如说，alibi原义为“不在犯罪现场的抗辩”，现义为“辩解，托辞”。答案为C。
