解析：这道题是关于系统去能化的问题。De-energize意味着去能化，也就是移除系统的电力。所以正确答案是C。
让我们通过一个生动有趣的例子来帮助你更好地理解这个概念。想象一下你的手机是一个系统，它需要电力才能正常工作。当你想要关闭手机时，你会按下电源按钮，这样手机就会De-energize，也就是移除电力，手机就会关闭。在这个例子中，De-energize就相当于移除手机的电力，让手机关闭。

A. The gyroscope will become stable before less than 15 seconds.
B. The gyroscope will become stable for at least 15 seconds.
C. After about 15 seconds, the gyroscope will become stable.
解析：这道题考察的是陀螺仪（gyroscope）的稳定时间。选项A说陀螺仪会在15秒之前就变得稳定，这是错误的。选项B说陀螺仪会至少稳定15秒，这也是错误的。正确答案是选项C，大约在15秒之后，陀螺仪会变得稳定。
要理解这个知识点，我们可以通过一个生动的例子来帮助记忆。想象一下你手里拿着一个陀螺，当你旋转它时，一开始它可能会摇摆不定，但随着时间的推移，它会逐渐稳定下来。就像一个孩子在玩陀螺时，需要一些时间才能让陀螺保持稳定，陀螺仪也需要一定的时间来达到稳定状态。所以，记住在大约15秒后，陀螺仪会变得稳定。
