D Correct answer
Explanation

When aircraft departing on the same route diverge by at least 45 degrees immediately after takeoff, reduced separation of 1 minute is permitted. This is because the diverging tracks quickly establish lateral separation, minimizing collision risk. This is a standard ICAO separation minima provision.
