Since the number is divisible by ‘9’, the sum of digits must be a multiple of 9.
4530xy = 4 + 5 + 3 + 0 + x + y
=> 12 + x + y
Now, x + y = 6 or 15
From the options, option (d) can be eliminated as 5 + 4 = 9 and we need the sum to be equal to 6 or 15.
Now, the best way to solve further is by using options and checking the divisibility for 7.
Option (b) and (c) will be eliminated Hence, option (a)
