A,B,D Correct answer
Explanation

Conductor processes are responsible for: (1) Starting section leader processes (which run osh) on each processing node, (2) Consolidating messages and writing to logs as the central coordinator, and (3) Running osh on the Engine machine specified by APT_ORCHHOME. Option C is incorrect because operators are executed by player processes, not directly by the conductor.
