HOW ARE THE CURRENT OPERATORS CREATING DEADLOCK HERE? 

Comments

I didn't see the options but but i think that

correct answer should be

wait(P) wait(Q) wait(P) wait(Q)

---

the Option that you tick

In that situation deadlock occurs

P_A S₁ (P = 0) | P_B S₃ (Q=0) | P_A (block at S₂) |P_B (block at S₄)

therefore , deadlock situation occurs

---

i think answer should be :

S1 : Wait(Q), S2 : Wait(P), S3 : Wait(Q), S4 : Wait(P)
