A male bee that performs no work and speaks monotonously is known as what?

The correct term for a male bee that does not perform any work is a drone. In the context of bee colonies, drones are specifically male bees whose primary role is to mate with a queen. They do not engage in the typical tasks carried out by worker bees, such as foraging for nectar and pollen, building the hive, or caring for larvae.

The characterization of "speaks monotonously" could metaphorically reflect the drone's limited role and lack of variety in activity compared to worker bees, which are bustling with action and contribute significantly to the hive's operations. The other terms listed do not relate to bees or their social structure: disdain refers to a feeling of contempt, discredit means to harm someone's or something's reputation, and dismal describes something as bleak or dreary. Thus, drone is the accurate and appropriate designation for a male bee in this context.
