The postfix expression is evaluated as follows:

1. Scan the expression from left to right.
2. When you encounter a number, push it onto the stack.
3. When you encounter an operator, pop two numbers from the stack, perform the operation, and push the result back onto the stack.

Let's evaluate the given expression 632*+:

1. Push 6 onto the stack.
2. Push 3 onto the stack.
3. Push 2 onto the stack.
4. Encounter *, so pop 2 and 3 from the stack. Multiply them to get 6. Push 6 onto the stack.
5. Encounter +, so pop 6 and 6 from the stack. Add them to get 12. Push 12 onto the stack.

So, the result of the postfix expression 632*+ is 12. Therefore, the correct option is 12.
