**Question 7:** Which of the following is equal to sequence \( u(n-2) \)? (a) \( 1 - u(-n+1) \) (b) \( u(n) - \delta(n) \) (c) \( 1 - u(-n) + \delta(n) \) (d) \( u(n) + \delta(n+1) \) --- This question presents multiple-choice options for determining an equivalent sequence expression. The expressions involve unit step functions \( u(n) \) and delta functions \( \delta(n) \).
