Find the ODD one out from the given options.

The position of the numbers are rearranged in every option as follows:

The odd number places are interchanged first and written together and then the even number places are interchanged and written together.

For instance in 7319, 7 and 1 are interchanged and 3 and 9 are interchanged to get 1793.

Similarly, the same process is carried out for other options.

As per this, option (1) violates this rule.

Hence 1975 has to be written as 7159. But its wrongly written. Hence our answer.
