The correct answer is: D. Hive : Bee

An incubator is a device that provides a controlled environment for hatching eggs. A hive is a structure that provides a home for bees. In both cases, the structure provides a safe and nurturing environment for the young to grow and develop.

The other options do not have the same relationship.

  • Archives are a collection of historical documents. A bullet is a projectile fired from a gun. There is no relationship between these two things.
  • A greenhouse is a structure that provides a warm and humid environment for plants to grow. A revolver is a type of gun. There is no relationship between these two things.

Therefore, the correct answer is D. Hive : Bee.
