QUESTION $1$

$2-$The next $4$ questions refer to the following situation:

In the provided blank, insert the letter that corresponds to the correct answer. For example, if the correct answer is $"$a$)1\mathrm{.}990",$ insert only $"$a$"$ as the correct answer.

The network below represents a project being analyzed by the critical path method. Activity durations $($included in below network$)$ are A$=5$days, B$=2$days, C$=12$days, D$=3$days, E$=5$days, F$=1$day, G$=7$days, H$=2$days, I$=10$days, and J$=6$days.
