Use the following information to answer the question.
In an investigation into sperm-oocyte binding, researchers isolated the egg receptor protein, ERB1, from the sea urchin Strongylocentrotus purpuratus. ERB1 binds to the sperm acrosomal protein, bindin, during fertilization. The researchers coupled the ERB1 receptor from S. purpuratus to plastic microbeads and then mixed the ERB1-coupled beads with sperm from S. purpuratus or from the related species, S. franciscanus. A summary of the treatment mixtures and a graph of the results are shown.
Treatments:
A: S. purpuratus sperm mixed with S. purpuratus ERB1-coupled beads
B: S. purpuratus sperm mixed with beads with no coupled ERB1 protein
C: S. franciscanus sperm mixed with S. purpuratus ERB1 beads
D: S. franciscanus sperm mixed with beads with no coupled ERB1 protein
Based on the description of the experiment, which of the treatments would be considered a negative-control treatment for S. purpuratus sperm binding?
A) Treatment A
B) Treatment B
C) Treatment C
D) Treatment D
