A-1, B-2, C-3, D-4 Explanation: Amdahl's Law ka formula hota hai: A. Serial Fraction (S) 1. Sets the absolute hard ceiling limit on system speedup Agar CPU cores ( ) infinite bhi kar diye jayein, tab bhi maximum speedup se jyada nahi ho sakta. Iss tarah overall speedup ki limit fix kar deta hai. B. Number of CPU Cores (N) 2. Determines the parallel scale factor denominator divider Formula me , parallel part ko divide karta hai, yaani ye parallel scaling factor ka denominator divider hai. C. Perfect Concurrency 3. Achieved if S = 0, giving speedup directly linear to N Jab serial part ho, tab ho jata hai, jise perfect linear speedup kehte hain. D. Performance Diminishing Return 4. Adding infinite cores yields no benefit if serial parts dominate Jaise-jaise cores ( ) badhate hain, zero ki taraf jata hai, jisse extra cores a
