Read the following article and select the best answer. Article: The next time you look up at the sky and see a cloud that looks like Mickey Mouse or your favorite fruit, look again. It may not be a cloud, but a Flogo -- a logo that flies. It's a new form of advertising in the sky that's never been used before. It's a different way to market your products, logos, and events. These funny logos are made with soap bubbles   mixed with a little helium gas   ,which makes them lighter than air and float in the sky. Special machines are used to make these new funny Flogos. The machine, which can be rented for $ 2,500 a day, can make a Flogo every 15-25 seconds. Flogos can fly much higher or lower if needed. They can last from a few minutes to an hour anywhere in the sky, depending on the weather conditions. Though they can fly up to 20, 000 feet, they usually float around at 300- 500 feet. Flogos are only white now, but people hope to have more colorful Flogos in the near future. Flogos are Green, 100% environmentally safe, because the soap used to make the Flogo comes from plants and leaves. So this fun way of advertising is healthy and good for the environment. Question: Which of the following can be the best title of the passage? - Machines -- Used for Flogos! - Flogos -- Logos that fly! - Advertising -- Made of Fruits! - Clouds -- Like Mickey Mouse!
(A).
Flogos -- Logos that fly!
