The question provides an incorrect multiplication result of 65589 and says that both the "5"s in the number are wrong, but all other digits are correct. This means the correct number should have the same "6", "8", and "9", but the "5"s should be corrected.

The number is: 65589  
To correct the two "5"s, we need to check the options that fit this pattern by changing both "5"s. The options are:

- 63489  
- 60489  
- 62689  
- 60689  

So, we substitute the wrong "5"s with correct digits.

By reviewing the options:
- 60489: This changes the two "5"s to "0" and gives a reasonable answer.
- Other options either don't change both "5"s or change more than needed.

The correct answer is **60489**, as the "5"s are replaced by "0".
