Parents can support academic improvement by following their child’s learning at home.
Why A is marked: Supervising schoolwork can help parents notice incomplete tasks, establish study routines, and offer encouragement.
Why the others are weaker: Extra tuition is not always needed, and remaining unconcerned removes useful support.
Question-quality note: Frequent, constructive communication with teachers can also help. Options A and D are both potentially beneficial, so the question would be stronger if it specified the kind of parental involvement being tested.
