There is only one sentence among these that contains a dependent clause, and that is the third option - Although the rain poured down, the Eagles and Panthers continued their soccer game.
The remaining sentences are all simple, meaning they contain only one independent clause (except for sentence 2, which is compound, meaning it has 2 independent clauses).
The correct answer is "Slang displays a tone that is too casual"
Slang speak is highly informal, sometimes even offensive. One should never use slang in a business setting because business deals should be kept highly informal and professional. Slang shouldn't be used under any circumstance as it may insult the people with whom we are talking by making it seem that we don't appreciate them or their business endeavors.
