The error in the sentence lies in part (B), 'lest you do not'. In English grammar, the conjunction 'lest' means 'for fear that' or 'in order that... not'. Because 'lest' inherently carries a negative meaning, it should not be followed by another negative word like 'not'. Using 'do not' after 'lest' creates an incorrect double negative. The standard grammatical structure following 'lest' requires either the subjunctive mood (the base form of the verb) or the auxiliary verb 'should'. Therefore, the correct phrasing should be 'Work hard lest you fail' or 'Work hard lest you should fail'. Part (B) is incorrect because it introduces 'do not', which contradicts the negative sense already established by 'lest'.
