Solution 1

The postfix expression is evaluated as follows:

  1. Substitute the values of a, b, c, and d into the expression. This gives us 2 2 * 3 4 * +.

  2. Start from the left and perform the operations as they come. The first operation is *, so multiply 2 (a) and 2 (b) together. This gives us 4.

  3. The expression now looks like this: 4 3 4 * +.

  4. The next operation is *, so multiply 3 (c) and 4 (d) together. This gives us 12.

  5. The expression now looks like this: 4 12 +.

  6. The final operation is +, so add 4 and 12 together. This gives us 16.

So, the correct answer is 16.
