The fisherman knows he won't live unless somehow he finds a way to defeat the genie. This is a very encouraging tale that shows the reader that it doesn't matter who you are or where you come from, you can outsmart whoever comes across you with clear thinking. The correct answer is the first one, the fisherman's determination to outwit the genie results in the climax.
The fisherman is not angry at the situation, perhaps upset that the genie has grown bitter with time and won't grant him any other wish but the manner of his death. The fisherman obviously doesn't want to die, so he "devises a plot", as the story says, and tricks the genie into going back inside the pot. The genie doesn't suspect a thing so he falls into the trap. Now the fisherman sets the new terms for the genie's release, which he complies. This is why the first answer is the most accurate one to the question asked.
