To find the sum of the digits in the integer obtained by subtracting 87 from 1067, we first need to calculate the result of the subtraction.
Subtraction: 1067 - 87 = 980
Now, we have the integer 980. To find the sum of its digits, we need to break it down into its individual digits.
- The rightmost digit is 0.
- The next digit to the left is 8.
- The leftmost digit is 9.
Sum of digits: 0 + 8 + 9 = 17
Therefore, the sum of the digits in the integer obtained by subtracting 87 from 1067 is 17.
So, the correct answer is option D) 589.
