Which option is NOT a flow state in AWS Step Functions?

In AWS Step Functions, a flow state refers to different types of states that control the flow of execution within a state machine. Each state type serves distinct purposes in orchestrating complex workflows.

The Pass state allows you to pass input to output without performing work, effectively enabling the transition of data between states without executing any action. The Choice state provides branching logic, allowing the workflow to take different paths based on conditions specified in the state. The Task state is utilized to execute a specific task, such as invoking a Lambda function or making a call to an API.

The term "Loop" does not correspond to a defined flow state in AWS Step Functions. While looping behavior can be achieved through iterative constructs like chaining states or using a combination of Choice and Task states, there is no dedicated state type named "Loop." Instead, developers implement loops through other means within the state machine design, emphasizing that AWS Step Functions does not explicitly provide a flow state called Loop.
