Consider a job scheduling problem with four jobs $$J_{1}, J_{2} J_{3}$$ and $$J_{4}$$, with corresponding deadlines : $$(d1_{1}, d_{2}, d_{3}, d_{4}) = (4, 2, 4, 2)$$

Which of the following is not a feasible schedule without violating any job deadline?

A

$$J_{2}, J_{4}, J_{1}, J_{3}$$

B

$$J_{4}, J_{1}, J_{2}, J_{3}$$

C

$$J_{4}, J_{2}, J_{1}, J_{3}$$

D

$$J_{4}, J_{2}, J_{3}, J_{1}$$
