Answer:
A). To show that the family is trying to prevent Liaqat from sharing certain information.
Step-by-step explanation:
The author most likely included this interaction(in this excerpt from 'Free the Children') is to display that the family was attempting to avert Liaqat from sharing certain information that could have led to undesired consequences. The point is substantiated by the reactions of translator and Iqbal's mother as displayed by the phrase 'raised his voice slightly', 'as if he had not given the answer they wanted to hear'. The family was trying to hide certain information that may lead to a serious issue. Thus, they are conscious of the information being revealed and hence, they are trying to prevent it from being revealed. Therefore, option A is the answer.
