Explanation

BGP path selection follows attributes in order. First, Local Preference is checked: routes B, C, and D all have 100 (better than route A with 0). Next, Origin Code is compared: "i" (IGP) is preferred over "?" (incomplete), so route B is less preferred. Between C and D, the MED is compared (lower is better). Route D has MED 0, route C has MED 20. Thus, Route D wins and is marked with ">".
