Correct Answer: The captain said, “The crew has to leave the ship at Liverpool.”

Solution : The correct choice is the fourth option.

In reported speech, the speaker conveys what someone else said without quoting their exact words. Direct speech, on the other hand, directly quotes the speaker's words, usually within quotation marks.

The process of transformation is as follows:

• In the given sentence, "said" will not change because the reporting verb does not have an object.
• The inverted commas will be used to quote the words of the speaker.
• The auxiliary verb "had" will be changed to "has".

Therefore, the direct form would be: The captain said, "The crew has to leave the ship at Liverpool."
