Which of the following is the correct direct form of this sentence? 'He said with joy that it was a very nice thing.'

Explanation: The correct direct form of the sentence is 'He said, What a nice thing it is!' (Option B). It properly reflects the exclamatory nature of the indirect sentence. Option A ('A nice thing it is!') is not exclamatory; Option C omits punctuation; Option D ('Which a nice thing it is') is grammatically incorrect. Note: Conversion from indirect to direct speech should preserve tone and punctuation.
