生物藥劑學課本原文：

The time period during which a drug product is expected to remain within the established product quality specification under the labeled storage conditions is generally termed “shelf-life”; however, this term is often used interchangeably with expiration period, expiry date, or expiration date.

生物藥劑學說架儲期(t90)通常也當作過期日期來看，所以照理來說這題答案應該是A，畢竟t90應該要比t50所耗時間短

補充：
另外又找到藥劑學課本原文說：
Expiration date: The date placed on the container label of a drug product designating the time prior to which a batch of the product is expected to remain within the approved shelf life specification, if stored under defined conditions, and after which it must not be used. 
藥劑學課本也把expiration date解釋為Shelf-life，所以我認為現在最適合的答案應該是A，如果有錯可以幫我提出，感謝
