Solution

The correct answer is C and D Only

Key PointsLet's analyze each option:

• The prefix notation is +/+A*DB - EFG
  • This is incorrect. The correct prefix notation for the given expression (A + B * D)/(E - F) + G is: + / + A * B D - E F G
• The prefix expression is the reverse of the postfix expression
  • The postfix expression for the given expression is: A B D * + E F - / G +
  • If we reverse this, we get: + G / - F E + * D B A
  • This is not the same as the correct prefix notation, so option B is not correct.
• The order of operands in infix expression and postfix expression are the same.
  • This statement is true. In infix notation (the typical mathematical notation), the operands are placed between the operators. In postfix notation, the order of operands remains the same as in infix notation.
• The order of operands in infix expression, prefix expression, and postfix expression are the same.
  • The order of operands in infix expression, prefix expression and postfix expression are the same" is true. Even though the arrangement of operators varies between these notation formats, the occurrence of operands remains the same.

So, the correct answer is 2) C and D Only.
