I'm taking a test and have to guess the right answer to the question after the article. Article: iPhone 6, which many people have been thirsty for, will be unveiled on September 9. It could go on sale to the public from Friday, September 19. Apple has launched a new iPhone every year since it unveiled the range in 2007, selling more than 500 million units since then, and has traditionally launched key products in September. The iPhone 6, Apple's ninth iPhone model, is expected to be released in two different sizes:4.7-inches and 5.5-inches. The smaller of the two will be available first. Like iPhone5, the new model will come in silver , gold and space grey. The iPhone 6 will be powered by new operating system iOS 8. Through iOS8, users will be able to monitor their health and fitness via HealthKit. HealthKit puts together numerous healthcare and fitness apps, such as blood pressure and heart rate monitors through partners including Nike, and allows them to communicate with each other. Users will be able to control home appliances and other connected devices through HomeKit, Apple's connected home framework. Similar to HealthKit, this app will organize your smart devices to control them in one place. One method of control will be via Siri-for example, you could tell Siri you were "going to bed", and it could dim the lights, lock your doors, close the garage door and set the room temperature. With the introduction of both of these key features, it's likely the iPhone 6 will take on even more of a lifestyle device role. It is designed to organize our lives and make everyday tasks easier and more efficiently completed. Suppliers are believed to be preparing to produce up to 80m of the new handsets by the end of December, according to the Wall Street Journal. In July, Apple announced strong financial results for its third quarter, with significant sales growth in China and profits ahead of expectations at $7.7bn. Question: If you are a customer, when can you buy an iPhone6? Options: A: After December 31. B: From September 19. C: After September 9. D: At the moment.
