How do you plan to solve it?

 

 

Code

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
        y = 8'h00; // default, avoids latchiong behaviour

        if (sel == 2'b00) begin
            y = a;
        end else if (sel == 2'b01) begin
            y = b;
        end else if (sel == 2'b10) begin
            y = c;
        end
    end
