A is right.
delay A to B = 4
A to D = 5
A to c =6.
then the table will be,
1st case, vector table of A via B
A B C D E F
0 4 8 8 7 6
via B B B B B B
2nd case
vector table of A via C
A B C D E F
0 10 6 8 13 10
via C C C C C C
3rd case
vector table of A via D
A B C D E F
0 6 8 5 8 11
via D D D D D D
comparing all the tables
final table is
A B C D E F
0 4 6 5 7 6
- B C D B B
