As the ratio of arrival rate to service rate is increased, utilization is also increased. This means that the system is being used more intensely, which can lead to longer wait times and slower movement through the system. Therefore, choice (B) is likely. Choices (A) and (D) are incorrect because they suggest that the system would become faster or more efficient, which is not generally the case when utilization is increased. Choice (C) is also incorrect because increased utilization means that the system is under more strain, not less.
