Solution

The correct answer is Both Statement I and Statement II are incorrect

EXPLANATION:

• Statement (I): "A thread is a dispatchable unit of work that does not execute sequentially and is not interruptible."
  • This statement is incorrect. A thread is a basic unit of execution within a process, and it does execute sequentially. Threads can be interrupted, and their execution can be preempted by the operating system scheduler, allowing other threads to run.
• Statement (II): "It is not possible to alter the behavior of a thread by altering its context when the thread is suspended."
  • This statement is also incorrect. The context of a thread includes its register values, program counter, and other execution-related information. When a thread is suspended, its context can be saved, modified, and then restored when the thread resumes execution. This allows for changes in the behavior of the thread.

Therefore, Statement I is incorrect, and Statement II is incorrect as well. The correct answer is option 2) "Both Statement I and Statement II are incorrect.".
