Let's use the divisibility rules for this:
Rule for 5: If the last digit is 5 or 0.
Rule for 6: If the number is divisible by 2 and 3.
Rule for 9: If the sum of the digits is divisible by 9.
51,483 is not divisible by all three.
45,803 is not divisible by all three.
81,450 is divisible by all three.
18,045 is not divisible by all three.
So, the answer is C. 81,450.
