Assertion (A): Multithreading on a multi-core processor can significantly improve application performance and responsiveness.

Reason (R): Threads within the same process share the same address space, global variables, and open files.

Choose the correct answer:

Explanation

Assertion (A) is True: Multithreading allows concurrent execution of multiple threads across different cores of a multi-core processor, which significantly enhances application performance and responsiveness.
Reason (R) is True: Threads belonging to the same process do share the same address space, global variables, and open files.
Correct Explanation: While statement (R) is a true characteristic of threads, the primary reason multithreading improves performance on a multi-core processor is the ability to run multiple threads truly in parallel across hardware cores, not just because they share an address space. Therefore, both are true, but R is not the correct explanation of A.
