How did Jonah end up inside the large fish?

The correct answer is that Jonah was thrown overboard. In the biblical narrative from the Book of Jonah, the prophet Jonah initially tries to escape God's command to go to the city of Nineveh by boarding a ship that travels in the opposite direction. A storm arises, threatening the ship and its crew. To save themselves, the sailors determine that the storm is a result of Jonah’s disobedience to God. They cast lots to determine who is responsible, and when it falls on Jonah, he admits his fault and suggests that they throw him into the sea to calm the storm. The sailors initially hesitate but ultimately comply with Jonah’s request, thus throwing him overboard. This act leads to Jonah being swallowed by a large fish, where he remains for three days and three nights before being vomited onto dry land.

The other choices do not accurately reflect the events of the narrative: Jonah did not jump in voluntarily, he was not swimming to be captured, and he was not involved in fishing at that moment. The specific context of being thrown overboard is crucial for understanding Jonah’s journey and the miraculous event that follows.
