Correct Answer (Detailed Explanation is Below)
A.
Infix
Detailed Explanation
Infix notation places operators between operands, such as A + B or A * B. When multiple operators are present,
operator precedence and associativity determine the evaluation order. Parentheses can explicitly change that order. For example, multiplication normally has higher precedence than addition. Prefix and postfix notations encode the operation order directly through the position of operators, so parentheses are generally unnecessary when the expression is properly formed.
