The appropriate option for the Direct Speech of the given sentence is: OPTION 2 "The manager said, 'Please have patience.'"

Here's why the other options are not ideal:

• The manager said to him, "you must have patience": This focuses on a single person instead of addressing the subject "us" in the original sentence.
• The manager said, "What a patience you have?": This is an interrogative sentence and doesn't convey the request from the manager.
• The manager said, "Do you have patience?": This is also an interrogative sentence and implies questioning someone's existing patience, not making a request for it.

"The manager said, 'Please have patience.'" directly conveys the manager's request to the group ("us") to be patient in a polite and respectful manner. It uses the imperative mood ("have patience") to make the request clear and avoids unnecessary additions or changes to the original meaning.
