Which sentence correctly avoids a double negative with the word ‘unless’?

Explanation

‘Unless’ already carries the meaning of ‘if not,’ so adding another negative word like ‘don’t’ after it creates an unintended double negative that reverses the intended meaning. The correct sentence, ‘Unless you study, you will fail,’ means the same as ‘If you do not study, you will fail,’ without needing an additional negative word.
