Answer: d. She should be using a disinfectant on her table, not just water.
Step-by-step explanation:
When Lakesha finished culturing the bacteria, she should not have used water alone to clean the surface of the table as water alone would not remove bacteria from the surface of the table if some got there.
She should instead have used a disinfectant on her table as this would have had better chances of significantly reducing the probability of contamination.
