Answer

Brief Explanations:

In aviation (a subfield of Engineering under Natural Science), anti - collision light regulations state that during nighttime operations, the anti - collision lights must flash at a rate of at least 2 flashes per minute. The first option is incorrect as anti - collision lights do need to flash at night. The second option is too vague; there are specific regulatory requirements for the flash rate, not just a general "sufficient to avoid collision" which is not a defined standard.

Answer:

The flash rate must be at least 2 flashes per minute.
