Campbell's has been marketing soup in Japan for more than 40 years. Early on, Japanese consumers were not receptive to ads featuring the Campbell Kids and the "M'm M'm Good" slogan. This compelled Campbell's to develop ads featuring a talking soup can known as "Mr. Campbell." Campbell's also developed soup varieties for Japan with fish as the main protein source and spices that reflect local preferences. As described here, which of the following strategies has Campbell's used in Japan:.
a. product-communications extension.
b. product extension-communications adaptation.
c. product adaptation-communications extension.
d. product-communication adaptation.
e. product invention.

D, product-communication adaptation

Explanation:

Product adaptation can be defined as the process of modifying a product to make it useful for a variety of users.

Communication adaptation can also be defined as the change in a product's communication as a result of a change in product strategy.

Product-communication adaptation can be defined as the modification of a product for a variety of users but ensuring that the marketing of the product is through standard communication channels.

In the case of Campbell adapted his product to look like M'm M'm Good product but ensured that he used a standard communication channel (ads) to market his product.

Cheers.
