Final answer:
Without information on the production rates of Plant A and Plant B, we cannot compare them to the fourth plant's production of 150 widgets in 60 days; therefore, the correct answer is 'Not enough information provided'.
Step-by-step explanation:
The question pertains to the production rate of a fourth plant which produces 150 widgets in 60 days and asks us to compare it to the productivity of Plant A and Plant B. Since no information about Plant A or Plant B is provided, we cannot make a comparison to determine whether the fourth plant makes more or less than the other plants. Therefore, the correct statement from the given options is D) Not enough information provided.
Comparing our information gap with a similar scenario where detailed knowledge about costs and sales figures is required to determine profitability (such as in a car manufacturing context), we recognize that without specifics about the production rates of Plant A and Plant B, we cannot make a reasoned conclusion on which plant has the highest or lowest production.
