Which of the following geographic descriptions approximately describes "Line A"?
- A.A line roughly parallel to and south of the border between the US and Canada (correct answer)
- B.A line roughly parallel to and west of the US Atlantic coastline
- C.A line roughly parallel to and north of the border between the US and Mexico
- D.A line roughly parallel to and east of the US Pacific coastline
Why"Line A" is a boundary that runs roughly parallel to, and south of, the US-Canada border. "Line A" is a boundary defined in the FCC rules that runs roughly parallel to, and south of, the US-Canada border, used to protect certain Canadian frequency allocations near the border from interference, answer A. It has nothing to do with the Atlantic or Pacific coastlines or the US-Mexico border, those are different geographic references entirely.
