e. a trade show aimed at industrial customers.
All the given options would be considered to be advertising.
Explanation:
Advertising is promoting one product for increasing its sales. This can be in various ways. Billboard is like a large hoarding for advertising found in the areas where there is huge traffic. If you find sample of a product at your doorstep, this is also a type of advertisement of that product.
Similarly, coupons clipped to the newspaper is an example of marketing the product that is clipped. Trade shows give an opportunity to the companies to showcase their new launches. They advertise them here. A point-of-purchase display is a special type of advertising where companies place the products (in a grocery store, for example) along with the merchandise they are promoting. So, all the given options are correct.
