A remark of FRQ LTGCGCC NW in Column 14 would indicate that ___ flashes per minute were observed.

The remark "FRQ LTGCGCC NW" indicates that frequent lightning strikes were observed in a specific area (to the northwest). The term "FRQ" stands for "frequent," which in meteorological observations typically refers to lightning occurrences that can be quantified. In this context, frequent lightning generally means that the observed flashes are within a certain range.

When looking at the provided options and understanding that "FRQ" specifically indicates a certain number of strikes, the range of 1-6 flashes per minute is appropriate for the frequency described. This frequency classification aligns with standard meteorological terminology, where "frequent" suggestively indicates more than occasional but not excessively high frequency.

Understanding the categorization of lightning frequency is important for interpreting weather observations accurately, especially for safety in aviation and outdoor activities. This classification helps meteorologists and pilots make informed decisions based on the level of electrical activity in the atmosphere.
