Show answer & explanation

Correct answer: D

Concept

Honeybee colonies contain reproductive and non-reproductive castes. Their sex follows haplodiploidy: fertilized diploid eggs develop as females, while unfertilized haploid eggs develop as males.

Queens and workers are female castes; drones are male. An established colony is ordinarily organized around one functional queen, and the sting is a modified ovipositor, so drones do not possess one.

Application

  • The word every is broader than the textbook description. An established colony ordinarily has one functional queen, but queenless transition states or brief queen overlap can occur; under a strict literal reading, the universal claim is overbroad.

  • The female-drone claim combines two facts: drones lack a sting, but they are males rather than females. Therefore the combined claim is false.

  • The shared-unfertilized-origin claim conflicts with haplodiploidy: workers arise from fertilized eggs, whereas drones arise from unfertilized eggs. Therefore this claim is false.

  • Regardless of whether the single-queen statement is read as textbook shorthand or strictly, both the female-drone claim and the shared-unfertilized-origin claim are false. Thus at least two listed statements are false.

Cross-check

The caste-development rule gives a direct check: fertilized and diploid corresponds to a female queen or worker, while unfertilized and haploid corresponds to a male drone. This independently establishes two false biological claims.

Result

Thus the applicable aggregate choice is More than one of the above.
