A semicolon is the best choice for this sentence. The first half of the sentence "Jonathan was not particularly hungry" is a complete idea. The second half of the sentence "he spent the meal picking at the food on his plate" is also a complete idea. When joining two complete ideas, a comma is not enough punctuation. It needs to have a conjunction as well. A semicolon is enough punctuation by itself and should not be paired with a coordinating conjunction.
The answer to your question would be option B. This would construct the sentence into, "Jonathan was not particularly hungry; he spent the meal picking at the food on his plate".
He said in both that all the suffering of all the people would pay off with equality between the two races and he spoke about his dream in both to. Oh just sayin bruh thts not really english thats history.
