Given that there exists a surjective function f : S -> T, which of the following substitutions for the sets S and T are possible? Select only one answer. (a) S = {1,2,3}. T= R. (b) S = {x ∈ R : x² - 4 = 0}, T = {5, π, -10} (C) S = {x ∈ R : (x² - 1)(x² - 4)=0}, T = {5,π,-10} (d) S = {1}, T = {x ∈ R : eˣ = 0}. (e) S = {n ∈ N : n ≤ 2022}, T={z ∈ Z : |z| ≤ 202}.
