In Chef Emilia`s signature dish, six distinct ingredients, labeled A to F, must be combined in a specific sequence. The sequence is partially known as follows: `--D-A-`. Ingredient B can be added before D or A. Ingredient C can be added before A, but not before D and ingredient E should be added at the end. Based on these hints, which of the following is the correct sequence of adding the ingredients?
a)E-F-D-A-B-C
b)B-C-D-E-A-F
c)C-B-D-F-A-E
d)B-F-D-C-A-E
