Solution
The correct option is B 1246
The given digits are 2, 1, 6, and 4.
The smallest number among all these digits is 1.
The thousands digit should be 1.
Among the remaining three digits (2,4, 6), 2 is the smallest number.
Hence, 2 should be the hundreds digit.
Among the remaining digits 4 and 6, the digit 4 is the smaller number.
Hence, the tens digit should be 4.
The remaining digit should be the ones digit.
Hence, the smallest number that can be formed with the given digits = 1246
