Transactional Memory & Concurrency Alternative List-I (Modern Approach) A. Software Transactional Memory B. Functional Languages C. OpenMP critical D. Lock-Free Algorithms List-II (Functional Strategy) Executes memory operations in blocks, rolling back if conflicts occur Avoids race conditions entirely by using immutable states Compiler directive that serializes execution blocks automatically Uses atomic hardware operations (like CAS) to avoid formal locks

A-1, B-2, C-3, D-4 Explanation: A. Software Transactional Memory -> 1. Executes memory operations in blocks, rolling back if conflicts occur Software Transactional Memory (STM) memory operations ko atomic blocks me execute karta hai aur agar koi conflict occur hota hai to rollback kar deta hai. B. Functional Languages -> 2. Avoids race conditions entirely by using immutable states Functional languages immutable states ka use karti hain, jisse state change nahi hota aur race conditions completely avoid ho jaati hain. C. OpenMP critical -> 3. Compiler directive that serializes execution blocks automatically OpenMP critical Directive compiler ko instruction deta hai ki wo code block ke execution ko automatically serialize kar de. D. Lock-Free Algorithms -> 4. Uses atomic hardware operations (like CAS) to avoid formal locks
