Critical Section Requirements List-I (Core Criteria) A. Mutual Exclusion B. Progress C. Bounded Waiting D. Remainder Section List-II (Formal Rule Definition) If a process is running in its critical section, no others can enter Only processes not in their remainder section decide who enters next There is a limit on how many times others can enter before a waiting process gets in Part of the program that does not access shared critical resources

A-1, B-2, C-3, D-4 Explanation: A. Mutual Exclusion -> 1. If a process is running in its critical section, no others can enter Agar koi ek process apne critical section me execute kar raha hai, to koi bhi dusra process apne critical section me enter nahi kar sakta. B. Progress -> 2. Only processes not in their remainder section decide who enters next Jo processes apne remainder section me hain, wo ye decide nahi karenge ki next konsa process critical section me jayega. Sirf wahi processes decision le sakte hain jo critical section me enter karne ke liye request kar rahe hain. C. Bounded Waiting -> 3. There is a limit on how many times others can enter before a waiting process gets in Kisi process ke critical section me enter hone ki request karne ke baad, dusre processes ko enter karne ka chance ek fixed limit tak hi diy
