Answer

Brief Explanations:

In construction excavation safety, workers above others on sloped or benched excavations can work only when lower - level workers have protection from falling objects. A miniature trench box may not be sufficient for all falling - object protection needs. Option C is not a comprehensive solution as it's hard to ensure no objects will fall. So, the key is overhead protection for lower - level workers.

Answer:

B. The workers on the lower level have overhead protection from falling objects
