Explanation:

Subordinating conjunctions introduce subordinate clauses. In the sentence "Another ubiquitous advertising type is the 'you've got to have it because look what it does' format, which demonstrates a product", the word "because" is a subordinating conjunction. The other options use "but" (coordinating), "and" (coordinating), or "that" (relative pronoun, not a subordinating conjunction in the relevant sense here). So this sentence includes a subordinating conjunction.

Answer:

Another ubiquitous advertising type is the "you've got to have it because look what it does" format, which demonstrates a product. (paragraph 6)
