How did Jonah end up inside the large fish?

In the biblical story of Jonah, he ends up inside the large fish (often referred to as a whale) after being thrown overboard by the crew of the ship he was on. This happens as a consequence of a violent storm that the ship encounters while fleeing from his divine mission to go to Nineveh. Jonah realizes that the storm is a result of his disobedience to God's command, and in order to calm the storm and save the crew, he instructs them to throw him into the sea. Once he's in the water, the fish then swallows him.

This answer correctly captures the narrative's deeper themes of accountability and the consequences of one's actions, as well as Jonah’s initial refusal to follow God’s instructions. The other options do not align with the text's details; Jonah did not jump into the water voluntarily, was not captured while fishing, nor was he swallowed while swimming, which reflects why these alternatives don't accurately represent the story.
