What does a Case statement allow in terms of execution paths?

A Case statement is designed to evaluate a variable or expression against a series of conditions and to execute the corresponding block of code for the first condition that evaluates to true. This means that within a Case statement, there can be multiple paths based on different possible values or conditions.

What makes option C the correct choice is that it highlights the capability of the Case statement to identify one true condition to execute its associated actions, while also allowing for a default action in case none of the specified conditions are met. The default path is generally defined to handle scenarios that don’t match any of the listed conditions, which allows structured control over the flow of execution.

In contrast to this, other options suggest limitations or characteristics that don't fully capture the functionality of a Case statement. For instance, the idea of multiple paths without a default execution does not align with how a Case typically functions, as it is designed to provide a reliable way to handle various conditions, including potential defaults. Similarly, constraints on executing a single path only under true conditions overlook the whole functionality of defining a default execution path. Sequential execution of statements is also not the primary design of a Case statement since it is focused on conditional branching rather than mere sequential execution.
