Answer:
(D) Coretta said, "I want to read that book!"
Explanation:
In writing sentences that have a conversation or dialogue, it is mandatory to put the speech within inverted commas.
In the first option, there is no closing inverted commas.
Option 2 is wrong in using the full stop right after 'said'.
Option 3 is also wrong in putting the exclamation mark outside of the inverted commas. So, the correct punctuation for the sentence will be -
Coretta said, "I want to read that book!"
