This question is of a higher difficulty. In the first look, all the statements seem to be connected to one another. Option 2 says 'it is the creator's participation and imagination that makes the single-panel comic so engaging and so rewarding'. The opening sentence of the para can have two possible opening sentences, 1 or 2 . Sentence 1 wants to give us an interesting example of inference, which can be found in single panel comics. To infer means to arrive at something on the basis of evidence. Single panel comic precisely has that. You are shown a panel and you have to imagine, through humor, what must have happened in the instant immediately before or immediately after... to get the joke you have to figure out (again inference). Thus 1 is a better opening sentence. 1345 forms a coherent paragraph. You might wonder why can't 2 be the opening sentence. 2 says it is the creator's participation...but here the creator is not participating, he is hiding something and the viewer has to use his imagination and arrive at hidden things through inference.
