$\huge\mathcal\orange{AnSwEr:}$

The child said that what a luck.

$\Large\mathfrak\green{♡ Hope \: it \: helps \: you! ♡}$

Answer 2

Answer: The child exclaimed what luck it was.

Explanation: When changing a sentence from direct to indirect speech, the double quotes as well as the comma are removed making it look something like this: The child said what luck!

Since there is an exclamatory mark at the end, the sentence is exclamatory, therefore the word "exclaimed" is used, just before the words between the double quotes.

The most important point when changing the sentence is that since direct speech is in present, and your are telling someone else something that happened earlier, i changes to past tense.
