Answer:
B.to inform readers about the inconsistencies in Iqbal’s story, and to persuade them that what is more important is Iqbal’s impact on the fight to end child labor is the correct answer.
Step-by-step explanation:
"Free the Children" is a book written by Craig Kielburger and Kevin Major, and it talks about a trip around Asia and how children grow up and work in poor conditions.
Since the mother gives new or contradictory information (such as the father being involved in the crime, his drug addiction and the carpet owner), readers can understand that there were inconsistencies in Iqbal's case. This would also help persuade readers that even Iqbal’s story is only one, it could be taken as something that happens all the time due to child labor, turning it the main conflict that should be stopped.
