Demand for a good is most likely to be more elastic when:选项：

Solution：C
The longer the time that has elapsed since a price change, the more elastic demand is. For example, if gas prices rise, consumers cannot quickly change their mode of transportation but will likely do so in the longer run.
中文解析：
价格变动后的时间越长，需求的弹性就越大。例如，如果汽油价格上涨，消费者不能迅速改变他们的交通方式，但从长远来看，他们可能会这样做。
