This comprehension question asks who helped or supported Adaeze in the story. After Adaeze found the crying child by the big tree, the passage states: "O wee kpoo ndi uwe ojii, ha kporo nwa ahu gaa ulo umuaka" - She called the police (ndi uwe ojii, literally "people of dark/black uniform"), and they took the child to the orphanage.
The ndi uwe ojii (police/law enforcement) were the ones who assisted Adaeze by responding to her call and taking the abandoned child to the children's home (orphanage). No other person is described in the passage as having helped her directly at that moment.
The other options are incorrect: Nna ya (her father), Onye nkuzi ya (her teacher), and Nwanne ya nwoke (her brother) are never mentioned in the passage as having played any role in helping Adaeze with the child.
