(A) number is divisible by $8$ if the number formed by its last three digits is divisible by $8$.In the given number $7236K2$,the last three digits are $6K2$.We need to check for which value of $K$ the number $6K2$ is divisible by $8$.If $K = 3$,the number is $632$. Since $632 / 8 = 79$,it is divisible by $8$.If $K = 7$,the number is $672$. Since $672 / 8 = 84$,it is divisible by $8$.Comparing this with the given options,$7$ is present as an option.

For what value of $K$,the number $7236K2$ is divisible by $8$?
