The way this question is stated isn’t clear and concise. The reason being is we have no information i.e(as mentioned before) about the project(s). We do not have an substantial information to qualitatively answer this question. However, I would take the second project because the cost variance is positive, a positive value means yours under budget meaning you have excess money which is great! And a negative schedule variance means yours not on the schedule. With this being said its unlikely to have negative SV and have a positive CV because if you’re not on the schedule this could mean you will need to spend more money in order to keep the project going i.e( paying over time, need more materials, people are taking vacations).
