To achieve the lowest possible maximum resource requirement, we need to find the critical path and then schedule the activities on the critical path for the earliest possible start.

The critical path for this project is ABCF, with a duration of 22 days. To complete the project within the 34-day deadline, the non-critical activities E and D need to be scheduled for their earliest possible start.

For an early start schedule, Activity D can start on day 1, followed by Activity E on day 4. Then, Activities A, B, C, and F can be scheduled on their earliest possible start dates, which are days 1, 1, 5, and 8, respectively.

This results in a peak resource demand of 14 on days 13 through 18, when both Activities C and F are in progress. Therefore, choice C is the best choice.
