Final answer:
The age group with the lowest workplace fatality rate is 55-64 years. The correct option is D.
Step-by-step explanation:
The age group with the lowest workplace fatality rate is 65 and older. According to the U.S. Census Bureau's Current Population Survey, the highest workplace fatality rates are typically experienced by younger age groups, such as those aged 18-24 and 25-34.
As people age, they tend to gain more experience and knowledge in their work, which can help reduce the risk of workplace accidents and fatalities.
Additionally, older adults may be more cautious and take better care of their own safety compared to younger individuals.
Therefore, the age group with the lowest workplace fatality rate is 55-64 years. The correct option is D.
