The advertising department for the Pennzoil Corporation is working on a print advertisement for a new product. At this point, the layout contains a phrase to attract attention, an additional phrase to provide an explanation, an illustration to show the product, and a paragraph to explain the advantages and benefits of the product. What other important element should be included?

C) signature

Explanation:

In marketing, signature refers to the identification of the advertisement's sponsor, i.e. the advertisement is paid for by whom. Generally if you see and advertisement for Coke, you can assume that the advertisement sponsor was the Coca Cola company, but other times advertisements are not that direct and straight forward.

But even in Coke ads, the sponsor must be identified, that is why the signature is necessary and it is generally placed in the bottom part of the ad written in a very small letter.

The answer is Signature.

Explanation:

We have a work at hand which is print advertisement for a new products. Several procedures such as designing a layout to attract attentions, imputing additional phrase to provide more explanations, an illustration to show the product, and providing a ground for stating the advantages and/or benefits amongst others have been factored as part of the ways of better positioning the product in the market.

It is thus in the light of the foregoing procedures that signature is imperative. A signature could be s personal name written in one's hand, with the intention of accepting, authenticating, and/or executing a document. The end result is that there's personification of all the positive elements associated with the firm and its products.
