A light described as a flashing light must flash at a minimum rate of how many flashes per minute?

Explanation:
A flashing light is defined by a regular, rapid sequence of bursts, specifically at least 120 flashes per minute (two flashes per second). This minimum rate makes the light clearly distinguishable at sea and quickly recognizable as a flashing signal, which is different from slower patterns used for other light characteristics. The options listed—90, 60, or 30 flashes per minute—do not meet that threshold, so they would not be described as flashing lights under the regulations. The essential point is that 120 flashes per minute is the standard minimum for a light to be classified as flashing.
