Question

Threads of a process share

Correct answer (D) both heap and global variables. Solution Threads within the same process share the same address space. This shared space includes: 1. Code segment : The executable instructions. 2. Data segment : Global and static variables. 3. Heap : Memory allocated dynamically during runtime. 4. OS resources : Such as open files and signals. Each thread maintains its own private stack, registers, and program counter . Therefore, threads share both heap and global variables. Turn this into a strength.
