The correct option is A Ovipositor
The stinging apparatus of the honey bee is a modified ovipositor (egg laying tube) that all bees and wasps have. In some bees and wasps, the ovipositor is nothing more than a simple egg-laying tube designed to get eggs into hard to reach nooks, while in others it is stiffened to allow holes to be made in wood or penetrate the bodies of other insects in order to lay eggs. As the stinger is a modified egg laying tube, only the female bees posses a sting.
