Option D is the closest to being correct. Although it has one mistake (Test 2 being run before Test 7), it respects most of the dependencies and prioritization better than the other options.

Modified Option D (correct version): Test 1 (no dependencies) Test 4 (depends on Test 1) Test 3 (depends on Test 4) Test 5 (no dependencies) Test 6 (depends on Test 5) Test 7 (no dependencies, but Test 2 depends on it) Test 2 (depends on Test 7) Test 9 (depends on Test 3) Test 10 (depends on Test 9) Test 8 (depends on Test 3)

It should be B because 5 is the first HIGH priority with no conditions.

D is correct, because if you run 5 first then you have to rrun 2 next because 7 is dependant on 2, that's why B cannot be correct, with D you get correct priority based on dependencies.
