The correct option is C. ^. Explanation of the Correct Answer In BASIC programming language, relational operators are used to compare two values. The result of a relational operation is a Boolean value, which can either be true or false. The common relational operators in BASIC include:

• < (less than)
• > (greater than)
• ≤ (less than or equal to)
• ≥ (greater than or equal to)
• = (equal to)

The symbol ^ is not a relational operator in BASIC. Instead, it is typically used as a bitwise XOR operator in some programming languages, or it may represent exponentiation in others, but it does not serve the purpose of comparing two values in BASIC. Why the Other Options Are Incorrect

• A. < (less than): This is a valid relational operator in BASIC. It checks if the value on the left is less than the value on the right. For example, 5 < 10 evaluates to true.
• B. > (greater than): This is also a valid relational operator in BASIC. It checks if the value on the left is greater than the value on the right. For example, 10 > 5 evaluates to true.
• D. ≤ (less than or equal to): This is a valid relational operator in BASIC as well. It checks if the value on the left is either less than or equal to the value on the right. For example, 5 ≤ 5 evaluates to true.

Summary of Key Points

1. Relational Operators: Used to compare two values and return a Boolean result (true or false).
2. Valid Operators in BASIC: Include <, >, ≤, and ≥.
3. Incorrect Option: The symbol ^ is not a relational operator in BASIC; it is used for other purposes in different contexts.
4. Common Pitfall: Confusing the use of ^ with relational operations; it is essential to know the specific operators used in the programming language you are working with.

Revision Summary

• Relational operators in BASIC include <, >, ≤, and ≥.
• The symbol ^ is not a relational operator in BASIC.
• Understanding the purpose of each operator is crucial for effective programming.
• Always verify the context of symbols in the programming language you are using.
