Concept:Converting indirect speech to direct speech requires reversing the tense and pronoun changes, especially for modals like 'would'.
Rule / Clue:'Would' in indirect speech typically comes from 'will' or 'shall' in direct speech. First-person pronouns usually use 'shall' for simple future.
Explanation:Remove the conjunction 'that'.
Change the pronoun 'she' to 'I' to match the speaker's original words.
Change 'would arrive' to 'shall arrive' because 'shall' is standard for first-person future intentions.
Add a comma after 'said' and enclose the direct words in quotation marks with a capital letter.
Option A follows all these steps correctly.
Option B uses future perfect tense ('will have arrived'), which would backshift to 'would have arrived' in indirect speech, not 'would arrive'.
Option C keeps 'would', which is not the usual direct source for a simple future statement.
Option D uses past perfect ('had arrived'), which remains unchanged in indirect speech and does not match the given sentence.
Answer:A. She said, "I shall arrive before noon."
