What data type does relational operators NOT work with?

Integers
Strings
Characters
Boolean

The correct answer is: Boolean

Relational operators work with all primitive data types except for Boolean values. Boolean values can only represent true or false, and therefore do not have numerical or string values to compare for relational operations. Integers, strings, and characters all have numerical or lexical values that can be compared using relational operators.
