/*Write solution code here*/
module selector3 (
    input [7:0] a,
    input [7:0] b,
    input [7:0] c,
    input [1:0] sel,
    output reg [7:0] y
);
    always @(*) begin
        if (sel == 2'b00) begin
            assign y = a;
        end else if (sel == 2'b01) begin
            assign y = b;
        end else if (sel == 2'b10) begin
            assign y = c;
        end else begin
            assign y = 8'h00;
        end
    end
