A. NT (nested task flag) = 1
B. NT (nested task flag) = 0
C. IF (interrupt flag) = 1
D. IF (interrupt flag) = 0
Answer:A
The IRET instruction gets back the execution state of the previous task, if
A. NT (nested task flag) = 1 B. NT (nested task flag) = 0 C. IF (interrupt flag) = 1 D. IF (interrupt flag) = 0
Explanation: If NT = 1, the IRET instruction gets back the execution state of the previous task. Otherwise, the IRET instruction lets the current task continue, after popping the required values from stack.
