Whether

The most appropriate option to fill in the blank is whether.

The sentence "Whether or not you allow me, I am going to the fair" is a disjunctive sentence, which means that it presents two mutually exclusive options. The speaker is saying that they are going to the fair regardless of whether or not the listener allows them to go.

The word "whether" is used to introduce a disjunctive sentence. The word "unless" is used to introduce a conditional sentence, which means that it expresses a condition that must be met in order for something to happen. The words "if" and "until" are also used to introduce conditional sentences, but they have different meanings. The word "if" is used to introduce a condition that is possible, but not guaranteed. The word "until" is used to introduce a condition that must be met before something can happen.

In the sentence "Whether or not you allow me, I am going to the fair," the speaker is not saying that they are going to the fair if the listener allows them to go. They are saying that they are going to the fair regardless of whether or not the listener allows them to go. Therefore, the most appropriate word to fill in the blank is whether.
