James conducted an experiment with 4 possible outcomes. He determined that the experimental probability of event A happening is 10 out of 50. The theoretical probability of event A happening is 1 out of 4. Which action is most likely to cause the experimental probability and theoretical probabilities for each event in the experiment to become closer?

A
removing the last 10 trials from the experimental data
B
completing the experiment many more times and combining the results to the trials already done
C
including a fifth possible outcome
D
performing the experiment again, stopping immediately after each event occurs once
