Synchronically, ( ) is viewed as the coexistence of various meanings of the same word in a certain historical period of time.
A、homonymy
B、hyponymy
C、polysemy
D、synonymy
【正确答案】：C
【题目解析】：本题考查polysemy（一词多义）。根据题干的关键词——various meanings of the same word（相同单词的多种意思），也就是一词多义。故C选型符合题意。homonymy——同音异义；hyponymy——上下义关系；synonymy——同义词，均可排除。
