Only option D represents system option A does not represent any system. Hence D must be the correct choice.

Yes @Mr. Khalique is absolutely correct.
Because the system equation must represent some response. So in option D, the response is given but not in A.

Sir, in this question objects are wrong please creation y(n) = y(n-1)+y(n+1).

Sir system output does not depends on depends on future I think there is no correct answer.

If option A is correct then option D also should be correct. Whoever the author of the question explain with correct answer.

I think A and D both are correct.
If it's true then we have to choose A as an answer because of priority of order.

The dynamic system depends only on past outputs or past inputs and not on future outputs, Hence option A and D can't be correct and option C is a static system. So option B may be the right answer.

Please tell me which is the correct answer?

Dynamic system depends on past Input and past output.

Dynamic system depends upon the past and future input and outputs. So in my view, option A and D are the correct answers.

Please, tell me the correct answer with the explanation.

The Dynamic system depends on present and past i/p o/p. So option b is correct.
Ranbir said:

Option A and D is correct because both past and future value depends, and the option A has more correct than D due to order.

Option A& D both are correct because both system satisfied condition of dynamic.

In Dynamic systems, output depends on present input as well as past or future inputs.

Both A and D is correct. But in above question there is a statement given that "one most appropriate". Now option "a" is more appropriate bcoz y(n) + y(n - 1) + y(n + 1) bcoz this dynamic system contains value of +-1 at the same time. If option "D" is given like y(n) + y(n - 3) + y(n + 3) then there is confusion between A and D. But here there is no confusion.

How system depends on future output? it is unrealizable and option B is correct.
Vimala said:

Option D is correct because A is not a system.
Joshi said:

As option A does not have the proper form of expression, so D must be the correct option.
Vani said:

Option A doesn't even show the equation of a system, hence option D is the more appropriate answer.

I think option B is correct.

Options A and D both are correct.
The dynamic system means having a memory which is represented by past and future o/p
At given present i/p.
