Answer:
b. stimulus generalization
Explanation:
This reaction from the overall market population is due to stimulus generalization. Since potential customers that have been in the market have already seen the products that Patek Phillippe has already introduced and saw them as high-end luxury products, then the market automatically places any future product that Patek Phillippe releases as in the same category. They do this without doing any research or analyzing the product, instead, they solely categorize new products as luxury due to Patek Phillipe's brand.
