Answer:
A. The sentence is fine as it is.
Explanation:
The given sentence is fine as it is. It is a complex sentence, which means that it consists of one independent and at least one dependent (subordinate) clause.
- I do my best to resolve it quickly. - independent clause
- When I have an argument with someone... - dependent clause
Option B is the second-best option. It's also a complex sentence, but it would be better to use when as the subordinating conjunction instead of while.
Option C is a compound sentence, which means that it consists of two independent clauses. I have an argument with someone isn't grammatically correct, which is why this option is incorrect. Option D is similar. The only difference is that the two independent clauses are separated.
This is why option A is the correct one.
