A Correct answer
Explanation

For aircraft using the same NDB (Non-Directional Beacon) navigation facility at or beyond 15 nautical miles, 30 degrees of separation is required. NDBs have less accuracy than VORs, requiring wider angular separation (30 degrees vs 15 degrees for VOR) to ensure adequate lateral separation between aircraft.
