Based on the data they collected using gel electrophoresis, label the branching tree diagram below. write the letters a, b, and c, to represent the possible evolutionary relationships between species a, b, and c

Some of the information needed for the question is not given. However, I know this question and the additional information that was needed. On the tree branching diagram the diagram should be labeled as B on the first spot, A on the second spot, and C on the third spot. Now, it can also be labeled A on the first spot, B on the second spot, and C on the third spot. Either will be correct, but I think B-A-C is the better choice. 

Iwould say silver and gold
