Livelock, Deadlock, and Starvation List-I (Concurrency Bug) A. Deadlock B. Livelock C. Starvation D. Priority Inversion List-II (Dynamic Thread Condition) Two or more processes are permanently blocked, each waiting for the other Processes continuously change state in response to each other without making progress A process is indefinitely delayed because others are prioritized A lower-priority thread holds a lock needed by a higher-priority thread

A-1, B-2, C-3, D-4 Explanation: A. Deadlock -> 1. Two or more processes are permanently blocked, each waiting for the other Deadlock ek aisi condition hai jahan do ya do se zyada processes permanently block ho jaate hain kyunki har ek process dusre process ke dwara held resource ka wait kar raha hota hai. B. Livelock -> 2. Processes continuously change state in response to each other without making progress Livelock me processes actively apni state change karte rehte hain ek dusre ko respond karne ke liye, lekin koi bhi real progress nahi ho pati hai. C. Starvation -> 3. A process is indefinitely delayed because others are prioritized Starvation (indefinite blocking) tab hota hai jab kisi process ko required resource endlessly nahi mil pata kyunki high-priority wale processes ko continuously favor kiya jata hai. D. Prior
