  • 0.4
  • 0.5
Show Solution

The Correct Option is C

Solution and Explanation

Step 1: Apply the steady-state error formula.
For a unit step input, the steady-state error is determined by the final value theorem or by evaluating the system's response at its steady state.

Step 2: State the conclusion.
The steady-state error for the system is calculated to be 0.4, thus option (C) is the correct selection.
