\hline \mathbb { K } & 10 & 140 & \
\hline \mathrm { L } & 8 & 64 & \mathbb { K } , \mathrm { M } \
\hline \mathrm { M } & 12 & 96 & \
\hline \mathbb { N } & 6 & 120 & \mathrm { M } \
\hline \mathbb { P } & 14 & 168 & \mathrm {~L} \

To determine the lowest resource requirements, we need to look for the day with the least amount of activities happening simultaneously.

If we operate on a late start schedule, we can determine the earliest possible start time for each activity.

Using this schedule, we can see that on day 15, only activity K is taking place since it has the earliest start time. Therefore, day 15 has the lowest resource requirements.
