The main idea is how memory and resources are organized. A process runs in its own isolated memory space with its own code, data, and system resources. A thread is a unit of execution inside a process, and all threads in the same process share that process’s memory and resources. This is why the statement that a process has its own memory space while a thread shares memory within the process is correct: it captures the isolation between processes and the shared environment among threads. Threads can access the process’s resources, which makes them efficient for performing concurrent tasks within an application, but they require synchronization to prevent data races. The other descriptions don’t fit this memory model: a thread does not have its own separate memory, a process does not share memory with other processes, and a thread can access the resources of its process.
