Since a worker devotes half-time (4 hours/day) to the project, the total hours can be calculated by adding the duration of all activities in days and multiplying by 4 hours/day. The critical path (longest path through the project) determines the total project duration. The critical path is A-B-D-E-F, totaling 5+4+6+6+6=27 days. Therefore, the total resources required are 27 days * 4 hours/day = 108 hours. However, none of the options exactly match this calculation, suggesting a possible misunderstanding in the question's setup or a mistake in the calculation. Given the options, 128 hours (D) is the closest incorrect choice, indicating a need for clarification or correction in the question or answer choices.
