Select the most appropriate option to fill in the blank.
______ he fulfills all the conditions, he should not be given the contract.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Unless.
Filler Concept: The word "unless" means "except if" or "if not," used to introduce a condition that must be met to avoid something.
Grammatical Explanation: The sentence implies that if he does not fulfill all the conditions, he should not be given the contract. So "unless" correctly expresses this negative conditional.
Option Analysis:
Lest — means "to avoid the risk of," usually followed by a negative verb, not fitting here.
Since — indicates cause or reason, not condition.
Whether — introduces alternatives or choices, not appropriate here.
Unless — correctly introduces the negative condition.
Final Sentence: Unless he fulfills all the conditions, he should not be given the contract.
Conclusion: The correct option is Unless.
