• C. 3689, 9863
• D. 3689, 8693

Answer 1

The correct option is C 3689, 9863

To find the greatest 4-digit number with the given digits, we arrange the digits in descending order.

And, to find the smallest 4-digit number with the given digits, we arrange the digits in ascending order.

$\begin{array}{cccc}\text{Thousands}& \text{Hundreds}& \text{Tens}& \text{Ones}\\ 3& 6& 8& 9\\ 9& 8& 6& 3\end{array}$

Since $3<6<8<9$ or $9>8>6>3,$ the smallest and largest numbers with the given digits are 3689 and 9863 respectively.
