Correct Answer: Option C — Generator A has a lower speed droop value than generator B and generator A will take a greater share of the load than generator B.

Speed droop establishes generator load-sharing characteristics in parallel operations. A lower droop percentage means the governor allows less speed drop from no-load to full-load, forcing the machine to pick up active (kW) load faster and accept a greater share than a machine with higher droop.
