All the co-efficients can have zero value
All the co-efficients are always non-zero
Only one of the static error co-efficients has a finite non-zero value
None of the above
Answer is Wrong!
Answer is Right!
The correct answer is: D. None of the above
The co-efficients of a closed loop system can be zero or non-zero, depending on the specific system. In general, there is no guarantee that any of the co-efficients will be zero.
Option A is incorrect because it is possible for some of the co-efficients to be zero.
Option B is incorrect because it is possible for some of the co-efficients to be zero.
Option C is incorrect because it is possible for more than one of the static error co-efficients to have a finite non-zero value.
In conclusion, the correct answer is: D. None of the above.
