. . . . . . . . you were the creator of the world! A. Unless B. When C. If D. Did

The correct answer is “If”.

The word “if” is used to introduce a condition or supposition. In this case, the speaker is asking what would happen if they were the creator of the world.

The word “unless” is used to introduce a condition that must be met in order for something to happen. In this case, the speaker is not asking what would happen if they were the creator of the world, but rather what would happen if they were not the creator of the world.

The word “when” is used to introduce a time when something will happen. In this case, the speaker is not asking what would happen if they were the creator of the world, but rather when they will be the creator of the world.

The word “did” is used to introduce a past action. In this case, the speaker is not asking what would happen if they were the creator of the world, but rather what they did when they were the creator of the world.
