Read the sentence.

the advertisement has a specific persuasive technique—it shows a stylish celebrity to encourage the viewer to buy a certain hair product.

(has) is underlined

which is the most accurate and precise replacement for the underlined word?

a. keeps

b. creates

c. uses

d. intends

C. uses

Uses is the only word that words in this context. The advertisement isn't keeping anything. It hopefully creates a desire in the consumer to buy a product but it doesn't create a technique. It also does intend to convince buyers but it can't intend a technique either. Techniques are used so this is the most accurate and precise replacement for has.
