Solution
The correct option is C 2789
Since it is a four-digit number, its place value chart will be as shown below.
The digits are 2, 8, 7, and 9.
Since we have to form the smallest four-digit number, the digit in the thousands place will have the smallest number, i.e., 2.
The digit in the hundreds place will have the next smallest number, i.e., 7.
The next smallest number, i.e., 8 will go in the tens place.
Finally, the biggest number, i.e., 9 will go in the ones place.
The smallest number so formed is 2789.
