A-1, B-2, C-3, D-4 Explanation: A. FCFS 1. Suffers from the Convoy Effect due to long initial processes FCFS (First-Come, First-Served) algorithm me agar ek lamba CPU burst wala process pehle aa jata hai, toh chhote processes ko uske peeche wait karna padta hai, jise Convoy Effect kehte hain. B. Shortest Job First 2. Can cause starvation for long-running processes SJF algorithm me hamesha chhote processes ko pehle priority milti hai. Agar continuously chhote processes aate rahein, toh lambe processes ko CPU nahi milta aur unka starvation ho jata hai. C. Priority Scheduling 3. Low-priority processes may stall indefinitely Priority scheduling me higher priority processes ko pehle execute kiya jata hai. Is waja se low-priority processes indefinitely stall (indefinite blocking/starvation) ho sakte hain. D. Round Robin 4. Hig
