Answer: C. It is in effect at all times
Explanation: Universal law, in its essence, contains the highest, invisible, ubiquitous principle or mind, which pervades everything on Earth and in the cosmos, and manifests itself in the form of "causes" or drivers of all human actions, deliberation, existence, philosophical determinations, etc. Every beginning of life, a conceived thought, every idea put into action, is a work of universal law. As no generation or epoch or part of history is not exempt from the initiative of universal law, this law works throughout the history of mankind, and long before that, it can be said that it is in effect at all times.
