Best Answer Explained in Below-:

In a switch-case statement, the types of values that can be evaluated are limited to certain integral types. Specifically, in many programming languages such as C, C++, and Java, the switch-case statement can handle integral data types like integers and characters. This is because these languages utilize switch-case for efficient branching based on discrete values.

However, floating-point types, such as floats and doubles, are not suitable for switch-case statements. The reason for this is primarily due to the nature of floating-point arithmetic, which can lead to precision issues. Floating-point numbers are represented in a way that can introduce rounding errors, making it difficult to match a float value precisely against case labels. As a result, allowing switches on floats would complicate control flow and could lead to unreliable behavior.

In summary, while integers and characters can be safely compared within switch-case structures, floats cannot due to precision-related challenges, making option C the correct answer.
