Based on your description that Scooter's company sells manufactured goods in large quantities, the most appropriate role in the value chain would be:
A. wholesaler
Wholesalers typically purchase large quantities of goods from manufacturers and sell them in smaller quantities to retailers or other businesses. However, if Scooter's company is also involved in the manufacturing of those goods, then B. manufacturer could also apply. Without more information on whether they produce the goods or simply resell them, A. wholesaler is the best fit given the context of selling in large quantities.
