Which of the following is an example of a telecommunications provider?

British Telecom (BT) is an example of a telecommunications provider because it primarily offers telecommunication services, including voice, broadband, and mobile services. Telecommunications providers are companies that facilitate communication over distances by electronic means. This includes traditional phone services, internet access, and mobile connectivity, all of which are core offerings of BT.

In contrast, the other choices—Amazon Web Services, Microsoft Azure, and Google Cloud Platform—are primarily cloud service providers. They focus on offering cloud computing capabilities, such as data storage, processing power, and various software services over the internet. While they may include some telecommunications functionalities as part of their offerings, their main classification lies in cloud services rather than direct telecommunications.
