Question

If I had been fighting I would have done it by day and not in the dark.

Answer 1

I believe that the correct answer here is the first option.

Here we see a narrator who is addressing a fight that has already happened and here we see that he is pride. We see that in his clear opinion of the fighting and the belief in his skill, because he would not wait for darkness, because he would not need that, as he is certain that he is good enough to win a fight in broad daylight. Here we see the narrators pride.

Answer 2

The tone of this sentence can best be described as conveying PRIDE.
What the speaker is saying in the sentence given above is that it is beneath him to fight in the dark. He makes it obvious that if he wants to fight, he would rather do it in broad daylight. This utterance shows the pride of the speaker in his ability to fight.
