Whilst you did not attach any advert or link to an advert, this is most likely the correct answer.
The purpose of marketing/ advertisement is to increase the demand for a particular good or service. When a company engages in advertising therefore, it is done to increase the demand for whatever good they are selling.
In this scenario, the company behind the advertisement is an energy bar company which means that the ad must be about increasing the demand for energy bars. Option B would therefore make the most sense.
