In the provided graphic, what exception will be thrown if an index is out of range?

The correct choice is IndexOutOfRangeException because this exception specifically deals with scenarios where an attempt is made to access an element of an array or collection using an index that is not valid—that is, the index is either negative or exceeds the size of the collection.

In programming, particularly with languages like C# that are utilized in UiPath, the IndexOutOfRangeException is a common runtime error that alerts developers when their code tries to reference an index that falls outside the boundaries of an available array or list.

Other exceptions listed do not pertain specifically to out-of-range index issues. For example, an ArgumentOutOfRangeException is typically related to arguments to methods that fall outside of the acceptable range parameter values, while NullReferenceException indicates that a reference variable is being dereferenced when it is null. InvalidOperationException indicates that a method call is invalid at the current state of an object. Thus, focusing specifically on the context of accessing array or collection indices, IndexOutOfRangeException is the accurate choice.
