Answer:
Hi!
It looks like the word you tried to underline with the --s is "it shows". Based on that, the answer to your question should be option C, Uses.
Step-by-step explanation:
If you picture this, the paragraph says that in order to encourage viewers to buy a hair product, a celebrity has to be seen trying the product on themselves.
The word keep does not satisfy this. If you change the word "shows" for "keeps", the meaning of the paragraph changes.
If you change the word "shows" for the word "creates", the meaning changes again, as you'd be implying the celebrity in the advertisement came up or made the product itself, which is not the original message.
The word "intends" is closer, but again, if you change the word in the example, the meaning changes.
However, if you use the word "uses" and swap it for the word "shows", the content of the message doesn't change and it depicts the message of a celebrity using a hair product to motivate people to buy it.
