Answer: Price and Quality (a. and c.)
Step-by-step explanation:
Price. This was one of the best choices. The price of the raw materials has a significant impact on the price Umami can charge for its seaweed snacks; therefore, price must be controlled.
Quality. This was one of the best choices. Umami is known for its high-quality snacks, and therefore located a high-quality supplier to manufacture high-quality products.
