Concept:Reported speech changes pronouns, tenses, and time words to match the speaker's perspective.
Explanation:Afua is reporting what she said to Ayuba, so "I" becomes "she" and "you" becomes "him".
The present tense "can't" becomes past tense "couldn't".
The future "will" becomes "would".
The time word "now" becomes "then".
Therefore, the direct statement "I can't help you now, but I'll call later" becomes "she couldn't help him then but would call him later".
Answer:Option B: him then but would call him later.
