When a number is divided by 10, the remainder is simply the last digit of that number.
In multiplication, the last digit of the product depends only on the last digits of the multiplicands.
The last digit of 14331433 is 3.
The last digit of 1422 is 2.
The last digit of 1425 is 5.
Now, multiply these last digits together = 3 × 2 × 5 = 30
The last digit of 30 is 0.
So, when 14331433 × 1422 × 1425 is divided by 10, so the remainder is 0
Hence, the correct answer is 0.
