The schematic map below shows a portion of a city area, including tunnels and bridges, Is it possible to take a drive around the city area using each tunnel and bridge exactly once, beginning and ending in the same place? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. Yes, because there is an even number of bridges and tunnels connected to each land mass OB. No, because there is an odd number of bridges and tunnels connected to at least one land mass. The complete list of such land masses is (Use a comma to separate answers as needed.) OC. Yes, because there are exactly two land masses with an odd number of bridges and tunnels. The two land masses are (Use a comma to separate answers as needed.)
