Native advertising:
D. Doesn't include a sales pitch.
Explanation:
Native advertising uses paid ads that have to match the look and feel and even the style of the content that is being put up on the website to market another product.
It is an effective way of advertising in a time when he advertising numbing of people has been an understood concept.
The people have learnt not to fall for sales pitches that used to work before so the market has had to adapt to this by using native advertising that is not using some sales pitch overtly.
