Use of conjunctions:

• A conjunction is used in sentences to join phrases, clauses, and words in one. They work as coordinators or subordinators of the sentence.
• The conjunction 'unless' is used when there is a condition as "except if".
• It shows the total dependence of the first part and the clause of the sentence on the other part.
• A condition as 'if' and 'only if' is applied and brought in when the conjunction 'unless' comes in a sentence.
• Here, the window shouldn't be open unless someone wants it to be.
• It is setting a condition and showing the dependence of the window being open/closed on the other person.
• The other options 'why', 'either', and 'for' are not counted as conjunctions in nature.
