Raymie Food Products Is Famous for Their Specialty Fruit Cake

Raymie Food Products is famous for their specialty fruit cake. The main ingredient of the cake is dried fruit, which Raymie purchases by the pound. In addition, the production requires a certain amount of direct labor. Raymie uses a standard cost system, and at the end of the first quarter, there was an unfavorable labor price variance. Which of the following would be a logical explanation for that variance?

A) The cost of workers' medical insurance plans jumped up dramatically during the quarter.
B) The factory lost two experienced workers at the beginning of the quarter, and their replacements wasted a large amount of materials during their training period.
C) The procurement manager was able to secure a volume discount on dried fruit, purchasing the fruit for less than the amount set by standard.
D) The production staff changed the work flow process so that production required fewer direct labor hours.
