Final answer:
The symbol <*>, presented as option D, is NOT a comparison operator. Symbols like =, <=, and > are valid comparison operators used in most programming languages.
Step-by-step explanation:
The student's question revolves around identifying which symbol is NOT a comparison operator commonly used in programming. In programming languages, such as Python, Java, and C++, comparison operators are used to compare two values. The options given are A) = B) <= C) > D) <*. The correct answer is D) <*, as it is not a standard comparison operator. Instead, the equals sign (=) is an assignment operator in most programming languages, while the less than or equal to (<=) and greater than (>) symbols are proper comparison operators.
