Which hive boxes can be utilized as brood chambers?

The correct answer is that both deep and medium boxes can be utilized as brood chambers.

In beekeeping, a brood chamber is where the queen bee lays her eggs and where the developing bee larvae are reared. Deep boxes have a greater volume, allowing for more frames and, consequently, more space for the colony to raise brood. Medium boxes, while slightly smaller than deeps, can also serve effectively as brood chambers if the hive's needs require it. This versatility in brood chamber options allows beekeepers to manage their hives based on specific conditions like colony strength and available resources.

While shallow boxes may be suitable for honey storage or as supers, they do not typically provide enough space for a healthy brood chamber. Therefore, the deep and medium boxes are the primary choices for brood rearing, making them the correct answers to the question.
