The lifespan of a honey bee drone is:A.4-5 monthsB.1-3 monthsC.6-7 monthsD.10-12 months

The lifespan of a honey bee drone is typically between 1 to 3 months.

Here is the detailed explanation:

Honey bee drones are male bees whose primary function is to mate with a queen. They do not contribute to nectar or pollen collection, and they don't have stingers. The drones are born in the spring or summer and live for only a short period of time. Their main role is to mate with a virgin queen during the mating flight.

Once the mating process is completed, drones die because their reproductive organs are torn away during mating. If they don't mate, they are often expelled from the hive before the onset of winter as they are no longer needed. Due to their relatively short lifespan and the absence of duties in the hive after mating season, drones live for about 1 to 3 months.

Therefore, the correct answer is: B. 1-3 months.
