To multiply two numbers, we usually use the traditional method of multiplication, which involves multiplying each digit of the second number by every digit of the first number and then adding the products.

In this case, we can start by multiplying 403 by the units digit of 27, which is 7:

403
  ×  27
   ------
    2821

Next, we multiply 403 by the tens digit of 27, which is 2, but shifted one place to the left:

403
   × 27
   ------
    2821
   12090

Finally, we add these two products to get the final result:

403
   × 27
   ------
   10881

Therefore, the answer is A) 10,881.
