\(\textbf{Detailed step-by-step solution: }\)


Starting from the rightmost column,
Take away 3 rods from 7 rods. The leftover is 4. So, 4 rods are left.
Take away 8 flats out of 8. There is no leftover. So, the digit at the ones place is zero.
Hence, the answer is 0.4.
An alternative solution using the place value table:


So, 8.7 − 8.3 = 0.4
Hence, option D is correct.
