Answer:
a) EC2 is an Infrastructure as a Service (IaaS) service provided by Amazon Web Services (AWS). It allows users to rent virtual machines (VMs) on which they can run their own applications and services. EC1, EC10, and Hybrid are not IaaS service providers.
Step-by-step explanation:
Infrastructure as a Service (IaaS) is a type of cloud computing service that provides users with access to virtualized computing resources, including virtual machines, storage, and networking. These resources can be used to run applications and services, and are typically provided on a pay-per-use basis. Amazon Web Services (AWS) is a leading provider of IaaS services, and its Elastic Compute Cloud (EC2) service is one of the most widely used IaaS platforms. EC1, EC10, and Hybrid are not IaaS service providers, and therefore cannot be considered as options for this question.
