Without the specific graph to reference, I can provide a general answer based on common evolutionary biology concepts.
If the graph suggests that most mutations cluster around the neutral or slightly negative fitness effects, then the correct answer would be:
**c: most mutations are neutral or slightly negative.**
This aligns with empirical observations in evolutionary genetics, where many mutations have little to no significant effect on fitness, and only a small proportion are strongly beneficial or harmful. If you have specific details from the graph to share, I could help further refine the answer!
