Consider the following situation:
Process 1 (P1): May request up to 2 s_1 resources and 2 s_2 resources.
Process 2 (P2): May request up to 2 s_1 resources and 3 s_2 resources.
s_1 is initialized to 4 s_1 resources and s_2 has 5 resources.

Suppose the current situation is that P1 has 1 s_1 resources and 1 s_2 resources while P2 has 2 s_1 resources and 0 s_2 resources.

Which of the following statements are true. Multiple answers are allowed but wrong results are penalized with negative marks (basically getting correct answer will get perfect but selecting all answers will get zero or negative marks). Assume the system uses deadlock avoidance policies.
