A company opting to boost its sales of branded footwear by offering buyers $500$ models$/$styles to choose from should consider reducing the $$15$ million annual costs for production run setup costs associated with producing $500$ models$/$styles at each production facility by

investing in production improvement option B at those production facility locations producing $500$ models.

cutting the percentage use of superior materials to help cover some $($preferably all$)$ of the costs of the $$15$ million in annual production run setup costs at each production facility producing $500$ models$/$styles$.$

instituting production improvement options A and C at each production facility where $500$ models are being produced.

producing no more than $200$ models at the company's production facilities in other regions.

doubling its expenditures for enhanced styling$/$features to also increase the S$/$Q ratings of its footwear brand.
