Answer:
c. attempting to add symbolic value to a product.
Step-by-step explanation:
Any product's symbolic value adds the meaning to its usage and reliability. It provides with a meaning apart from its material value. It makes the consumer go for it as it gives reliability of the product. The symbolic value gives a reference to the immaterial nature of the object. In the above case, Hallmark's product attains much value as the print of his name adds value to the product.
