Your answer would be choice A
This is a debatable topic and there are many claims/arguments that both sides can use, thus this is more reliant on the speaker's opinion. For example: It is more difficult to keep bias out of video because the video shows an like a car crash and it is blatantly obvious this "x" was at fault for the car crash. Or it is not harder but the same because the vocabulary and wording can be manipulated in ways to imply a different story than what has truly transpired. It is just pretty much up to you.
Your answer is very correct
