Best answer

A. One such number is $4$.
C. $36$ satisfies those conditions.
D. Smallest such number is $19$.

Option B is not possible.

$6 = 3 \times 2\\9 = 3 \times 3$

So, if a number $n$ is divisible by $9$, then it is either divisible by $6$, or leaves a remainder of $3$ when divided by $6$.

Hence, option B is our answer.
