Answer 1

The correct option is C 9742

To get the largest 4-digit number from the given digits, we arrange the digits in descending order.

Since $9>7>4>2,$ we have 9742 to be largest 4-digit number that can be formed from the given digits.

$\begin{array}{cccc}\text{Thousands}& \text{Hundreds}& \text{Tens}& \text{Ones}\\ 9& 7& 4& 2\end{array}$
