A manufacturing company's annual report details production costs (in thousands of USD) for its three product lines (Alpha, Beta, Gamma) across four quarters. The table below provides this data. If the company aims to reduce total production costs for products with an average quarterly cost exceeding $150,000, which product line(s) should it prioritize?
✓ Correct Answer: Option C
Calculate the average quarterly cost for each product: Alpha = (120+180+160+140)/4 = 150; Beta = (170+150+190+130)/4 = 160; Gamma = (110+100+120+130)/4 = 115. Only Alpha and Beta have average quarterly costs of $150,000 or more.
