Sentence improvement (sequence of tenses) — Choose the form that correctly maintains tense agreement in: ‘‘John had told me that he hasn’t done it yet.’’ Make the reported clause and reporting verb consistent.

Given sentence
‘‘John had told me that he hasn't done it yet.’’

Concept/Approach
Keep the present relevance of ‘‘hasn't done it yet’’ by using a present reporting verb. Present perfect (‘‘hasn't done’’) pairs naturally with present reporting (‘‘tells’’). Alternatively, a full backshift would be ‘‘told … hadn't done’’; however, among the choices the best fix is to change the reporting verb.

Option analysis
A: told — Would require ‘‘hadn't done it yet’’ for consistency; not offered together.
B: tells — Correct: ‘‘John tells me that he hasn't done it yet.’’C: was telling — Progressive past mismatches the continuing present relevance in the that-clause.D: No improvement — Original mixes past perfect with present perfect awkwardly.

Final Answer
tells
