Answer:

C. 157

Step-by-step explanation:

Safety stock = Z-score * Standard deviation of average demand * √lead time

Z-score for 74 % service level is 0.643

Standard Deviation of demand is 200

Lead Time = 1.5 weeks

Safety stock = 0.643 * 200 * √1.5

Safety stock = 0.643 * 200 * 1.224745

Safety stock = 157.502
