To calculate the due date with a 99% likelihood of project completion, we can use the formula:

Due Date = Expected Completion Date + Z-score x Square root of Project Variance

The Z-score for a 99% confidence level is 2.33.

So,

Due Date = 68 + 2.33 x √21
            = 68 + 2.33 x 4.5826
            ≈ 79 days

Therefore, the best choice is C) in 79 days.
