A traditional PERT analysis $($i$.$e$.,$ based only on critical path$)$ for a project with multiple paths found the project duration mean of $100$ days with variance of $20.$ The standard deviation of individual activities in all parallel paths is about $10\%$ of the respective means. A Monte Carlo simulation was carried out for the same project. Which of the following could be the mean and variance respectively generated for the project via simulation:

A$.$

$90$ and $12$

B$.$

$110$ and $12$

C$.$

$110$ and $25$

D$.$

$90$ and $25$
