The correct answer is D. As long as it doesn't rain tonight, the game will begin are 8 p.m.
Step-by-step explanation
The conditionals is the name of a grammatical structure that serves to speculate on what could happen, have happened and what we want to happen. Two sentences are used in this structure, in which the first sets a condition for the second to be possible. For example "As soon as my parents give me permission, I will go to the party with my friends." The word "if" is also often used as a conditional, however it is not mandatory to use it. According to the above, the correct answer is "D. As long as it doesn't rain tonight, the game will begin are 8 p.m". Because the first part of the sentence conditions with the phrase "As long as it doesn't rain tonight" and then speculates on what would happen "the game will begin are 8 p.m"
