If you think you've found the right answer choice, do you feel it is still wise to read through the other answer choices carefully? And how much time would you spend reading through those other answer choices? This is assuming a real-life testing scenario.

If you're not sure about the argument, nor are you confident, yes, read all the answer choices and use the process of elimination to confidently choose the right answer.
So, yes. Either way, I tend to look over all the answer choices.
For LR and RC, DO read every answer choice and eliminate with confidence. Assume that you're always liable to make assumptions, and mitigate the risk inherent in this tendency by eliminating wrong choices with certainty. In other words, don't rely on your certainty that an AC is correct: bolster that certainty with certainty that the other AC's are wrong.
Test taker: "A... nah.. B... eh... C... yup. Move on." Oh but C used the word "many" and the correct answer needed the word "most." As it turns out, E was almost identical to C except for this difference. They got ya.
It doesn't take much time to just quickly peek. If your answer is really correct then it shouldn't phase you to see a few more wrong answers.
BUT this can also be used against you. On those big huge long parallel reasoning questions at the end with formal logic and slightly different modifiers, test takers have statistically been shown to make A the correct answer a lot of the time, simply because they know people won't trust their judgment on A without checking the rest, and thus it becomes a time-sink.
