A(n) _____ should be used to specify all the exception types when being handled by a single exception handler.

Using a tuple to specify all the exception types that a single exception handler should catch is appropriate because tuples are immutable and can hold a fixed number of elements. When defining a tuple of exceptions, it ensures that the collection of exception types cannot be altered after its creation, which is a desirable property when establishing the types of errors that should be handled together.

Tuples also allow for easy and clear grouping of multiple exception types, making the code more readable. For instance, in Python, you can write something like except (TypeError, ValueError):, where the parentheses denote a tuple of exceptions. This creates a clean and concise way to manage error handling for different types of exceptions that are logically related.

In contrast, while lists, arrays, or dictionaries could theoretically hold exception types, they are either mutable (lists and dictionaries) and create a risk of changing the intended handling behavior or are not as commonly used in this context as tuples. Tuples are the preferred choice in this scenario due to their simplicity, clarity, and immutability, effectively signaling that these exceptions should be treated as a single group for the purposes of exception handling.
