The correct option is C 3
To check the divisibility of a number with 4, we need to check the tens and units digits and see if the number formed by them is divisible by 4 or not.
In 4999, we need to check 99.
99 is not divisble by 4, we can subtract 3 from it, so that we get 96.
96 is divisible by 4, so the smallest number to be subtracted from 4999 is 3 to get 4996, which is divisible by 4.
