Option D. a-2, b-3, c-4, d-1. Answer & Solution Answer: Option D No explanation is given for this question Let's Discuss on Board

List-I	List-II
a. $α^{n} u (n)$	1. $\frac{α z ^{- 1}}{( 1 - α z ^{- 1} ) ^{2}} ROC : ∣ z ∣ > ∣ α ∣$
b. $- α^{n} u (- n - 1)$	2. $\frac{1}{( 1 - α z ^{- 1} )} ROC : ∣ z ∣ > ∣ α ∣$
c. $- n α^{n} u (- n - 1)$	3. $\frac{1}{( 1 - α z ^{- 1} )} ROC : ∣ z ∣ < ∣ α ∣$
d. $n α^{n} u (n)$	4. $\frac{α z ^{- 1}}{( 1 - α z ^{- 1} ) ^{2}} ROC : ∣ z ∣ < ∣ α ∣$
